Mini Environmental Meters

Mini Environmental Meters

Major Tech has made a range of mini environmental meters available to its South Africa customer base. There are four different meters, all designed and manufactured to the high standards Major Tech is known for.

MT90 Mini Thermo-Anemometer
The first device is the MT90 Mini Thermo-Anemometer which is used for measuring air temperature and velocity. The device includes a dual-line, four-digit LCD display with a backlight. It is also equipped with Bluetooth to make it easy to transfer data from the MT90 to the user’s Android or iOS smartphone using the Meterbox Pro app.

The air velocity can be measured in m/s, km/h, ft/min, or knots, while temperature is measured in degrees Celsius or Fahrenheit. The MT90 can continuously measure the temperature and velocity over time, providing the user with the minimum, maximum and average readings.

A low-battery display will alert you when the 9V battery is running low, while the auto power-off function will turn the MT90 off if it has not been used for 10 minutes.

MT91 Mini Hygrometer
The MT91 Mini Hygrometer measures the ambient temperature (-20 to +60 degrees Celsius) as well as the relative humidity and displays the data on a dual-line, four-digit LCD display with a backlight. Temperature is measured in degrees Celsius or Fahrenheit, while humidity is expressed as a percentage.

The MT91 includes Bluetooth to transfer data to the Meterbox Pro app on the user’s smartphone, while calculating minimum and maximum values over a period of time. The low-battery function warns if the 9V battery power is getting low, and the device is set to automatically power-off if unused for 10 minutes.

MT95 Mini Sound Level Meter
The MT95 is used for acoustic measurements in a variety of environments, from factories to offices to schools. It is used for noise engineering, sound quality control and health & safety operations, and can measure sound in a range of 35dB to 130dB. Readings are displayed on a 4-digit LCD display.

It features a 0.5-inch electret condenser microphone. An electret is a ferroelectric material that has been permanently charged, removing the need for a polarizing voltage to operate the microphone. The MT95 measures both A and C weighted sound levels and includes a background sound absorber.

Running off one 9V battery with low-battery alerts, the MT95 will automatically power-off after 10 minutes of inactivity.

MT96 Mini Particle Counter
The MT96 Mini Particle Counter measures the particle mass concentration in the air, along with the air temperature (0 to 50 degrees Celsius) and relative humidity. Major Tech is the first company to offer an instrument containing a combination of these measurements in one meter, designed to measure air quality as well as for energy saving tests.

The device simultaneously measures PM2.5 and PM10 particle density. PM10 is particulate matter 10 micrometres (μm) or less in diameter, while PM2.5 is particulate matter 2.5 μm or less in diameter – about 3% the diameter of a human hair.

Readings are displayed on a 2-inch TFT colour LCD display and data can be transferred to the user’s smartphone via Bluetooth. Sampling time can be set from 30 seconds to 5 minutes and the data collected is automatically saved to the instrument’s memory, which holds about 5,000 measurements.
The user can also set the automatic power-off function to shut the instrument down after 3, 10 or 30 minutes of inactivity in order to save power on the 3.7V Li-Ion battery.

K2007R 1000A AC Clamp Meter

K2007R 1000A AC Clamp Meter

The K2007R 1000A AC TRUE RMS clamp meter from Major Tech is a testing tool that permits current measurements on live conductors without interrupting the circuit. The K2007R is an indispensable addition to the technician’s toolbox as its 33 mm diameter tear drop jaw makes it easy to work in tight spaces.

More than simply a current meter, the K2007R offers three functions in one:

  • A True-RMS current meter. AC is represented as a sine wave with changing amplitude, which means current measurements can vary at different points in time. True-RMS (root mean square) converts AC signals into similar DC signals and this provides a more accurate AC reading.
  • A True-RMS voltage meter.
  • A resistance meter. Measured in Ohms, resistance a measure of the opposition to the passage of current through a conductor.

The K2007R clamp meter can measure AC current up to 1000A and AC/DC voltage up to 600V. A resistance of up to 6kΩ can also be measured and it includes an audible continuity tester. If there is a circuit fault (a continuity of below 90Ω), the continuity buzzer instantly alerts the technician of a problem without requiring him/her to look at the meter.

The ergonomically over-moulded body has been designed to ensure comfort and convenience, allowing safe one-handed operation, while readings are presented on the clear LCD display. Test leads with protective caps are included in the box, along with two R03 1.5V batteries which provide about 170 hours of continuous measuring time.

A low-battery warning is displayed when the batteries fall below normal operating voltage and a sleep function automatically powers the device off after 10 minutes of inactivity.

To assist technicians in taking readings, the HOLD button ensures that the current reading is retained on the LCD display until it is dismissed. This allows for accurate measurements in hard to reach and dark spaces where instant readings may be misread.

Designed to the highest quality standards, this instrument has been tested according to International Electrotechnical Commission (IEC) 61010-1 standards: CAT IV 300V and CAT III 600V. The K2007R is also rated IP40 to prevent the intrusion of small objects.

AC Current Clamp Meter with Data Logger

AC Current Clamp Meter with Data Logger

The MT745 from Major Tech is a clamp meter used to measure the AC current running through an electrical conductor in tight spaces. It permits electricians to measure the current without touching the conductor or having to disconnect the supply from the conductor.

The MT745 includes a large backlit LCD display to make it easy to read the measurement, which can be in the range of 0.5A to 3,000A. Pressing the “hold” button on the current meter will keep the latest readings on the screen, while the built-in Bluetooth communication allows users to send data to the Meterbox app on their smartphones.

The device has a sample time of 200 milliseconds. The data logger keeps 16 320 measurements, and users are presented with an analogue bar graph, and can also view the frequency and inrush current. The MT745 uses two LR6 batteries and to save power the instrument will automatically power down after 15 minutes of inactivity.

The flexible current coil is 457 mm in length. The Meterbox Pro app is available for Android and iOS smartphones at no charge.

Heavy-duty True-RMS Multimeter

Heavy-duty True-RMS Multimeter

The MT1005 is a heavy-duty True-RMS industrial digital multimeter for measuring AC/DC voltage and current, resistance, capacitance, frequency (electrical and electronic), duty cycles, diode testing, continuity and thermocouple temperature.

The device is equipped with a large 50 000 count, 320 x 240 TFT colour LCD display and provides fast A/D converting sampling time, high accuracy, built-in data logging and trend capture functionality. It offers 4mA to 20mA process loop measurements with a percentage reading, and operates in a temperature range of -200°C to 1350°C.

It traces any equipment interruptions and records the events on the device for future review. Not only does the MT1005 trace interruptions and record the events, it can also memorise datasheets and transfer this, and other data to a PC or a smartphone via Bluetooth.

A True-RMS-meter can measure both pure waves and non-sinusoidal waves more accurately. Nonlinear loads, such as variable speed drives or computers can distort waveforms and an average responding meter can be as much as 40% lower or 10% higher in its calculations when measuring distorted waves.

The battery-powered multimeter includes a Li-ion rechargeable battery that provides around 6 hours of operating time, and the AC adaptor to charge the system is included in the box. A low-battery warning will alert users when the voltage drops below the required operating voltage, and the MT1005 also offers an automatic power-off function that the user can set to between 5 minutes and 30 minutes – or it can be disabled completely.

With a wide range of features and double-moulded housing to ensure it handles tough conditions, the MT1005 is ideal for heavy-duty usage. Major Tech also offers a range of accessories for the device, from clamp on adaptors to additional batteries, leads and probes.

Are your lights and lamps EMC approved?

Are your lights and lamps EMC approved?

Have you ever noticed your radio making crackling noises when your cell phone rings? Or have you ever seen waves and strange noises on your television when your mobile is near, and it receives an SMS? What you’re seeing and hearing is electromagnetic interference (EMI).

EMI is a disturbance generated by electrical or mechanical equipment, which can include ignition systems, cellular networks, lighting and many others. EMI in our daily lives is more of an annoyance than anything else, but it can cause problems, such as when your garage door opens when you try to change the TV channel with the remote. In extreme cases it can degrade the performance of an electrical circuit or even stop it from functioning altogether – such as disrupting the functioning of critical equipment like pacemakers.

To ensure that electrical and mechanical components don’t cause any EMI, the South African Bureau of Standards (SABS) and the Independent Communications Authority of South Africa (ICASA) have set standards that electrical equipment must adhere to. This is in line with international standards on Electromagnetic Compliance (EMC).

EMC standards regulate the electromagnetic emissions from equipment to ensure they don’t interfere with other equipment. The standards are also designed to ensure that equipment is reasonable immune to this type of interference, although one can’t judge what the interference strength of non-compliant equipment may be.

All lamps and lighting products sold in South Africa, must be “EMC Approved”. Unfortunately, in South Africa these standards are not always followed, and many lamp and lighting products are not EMC Approved, which means they may interfere with other equipment, or be subject to interference.

When purchasing these products, buyers are advised to check that their chosen devices are labelled as EMC Approved. It’s also a good idea to make sure the company that manufactured your products is a reliable and trusted brand. You may find a cheap product that looks great, but if it hasn’t been EMC Approved you could be in for a surprise. More importantly, if the product you like is not EMC Approved, it may be worthwhile asking “Why?”.

All lamps from Major Tech have been through the approval process to ensure they meet the EMC Approved standards and can be used anywhere in the world. The same applies to Veti products. Before any lamp and lighting products are made available to the public, they all go through the compliance process and are certified as EMC Approved, allowing customers to opt for Veti and Major Tech products with confidence.

Major Tech has also released a square PP3 Maxi Alkaline battery operating at 9V, which are available as individual items. For remote controls and other wireless devices, an A23 battery operating at 12V is also available in packs of five or as individual items.

The more affordable Super Heavy Duty range of batteries is also available for hobbyists and people looking to run everyday devices. As with the Maxi Alkaline batteries, they are available in a variety of sizes.

The AAA and AA batteries are available in packs of four, while the C- and D-size batteries are available in packs of two. The 9V PP3 batteries are available as individual items.

To make it easy to differentiate the two ranges, the Maxi Alkaline range is recognisable as a silver battery with an orange stripe, while the Super Heavy Duty batteries are silver, with an orange stripe and a blue top.

Although the two ranges are available at different price points, they have been manufactured to the quality standards Major Tech is known for. The company conducted an in-depth search for a manufacturer that could deliver the quality of battery required, and the range will be supported by Major Tech’s nationwide footprint.

Solar Power Floodlights

Major Tech has launched a range of solar-powered floodlights to ensure customers can light different environments in remote areas without an electricity supply, or when Eskom is unable to supply electricity. There are three products in the range of floodlights using 8W, 10W or 20W of power.

8W LED with PIR

The SFP83 is an energy-efficient 8W solar-powered 88 x 2835 SMD LED floodlight with a built-in PIR (Passive Infrared) sensor. The PIR sensor continuously scans the operational zone for a moving heat source. When movement is detected, it automatically switches on the light. The sensor can be adjusted to scan an area of 8 metres to 10 metres and the light can be set to burn for between three seconds and four minutes.

The 8W LED produces 500 lumens and is IP44 rated. IP stands for “Ingress Protection” and the 44 rating means the system is protected from ingress by most wires, slender screws, large ants etc., as well as splashes of water, such as rain.

The solar panel measures 120mm x 210mm and charges a 7.4V 1800mAh battery, which can keep the light on continuously for about 70 minutes.

10W LED floodlight

The SFR105 is an energy-efficient 10W solar-powered LED floodlight that produces 600 lumens. The 195mm x 195mm Aluminium solar panel charges a 3.7V 4000mAh Lithium Phosphate battery that will keep the floodlight on for about 8 hours at 100% output.

Designed for the outdoors, the SFR105 is resistant to rust and is IP65 rated, which means it is completely dust-proof and can withstand jets of water directed at it. The system includes a 3-metre cable, allowing the panel to be positioned away from the light.

The floodlight is controlled by a remote control which can activate the light and set up automatic activation times. Timer options are for three, five or eight hours, and the user can choose to have the floodlight working at 100% or 50% power.

20W LED floodlight

The SFR210 is a solar-powered LED floodlight that produces 1000 lumens. It is IP65 rated to keep dust and water out and casts a light beam at a 120o angle.

The Aluminium solar panel measures 250mm x 350mm and powers a 3.7V 8000mAh Lithium Phosphate battery that can provide over eight hours of operation at 100% power. A 3-metre cable is included to allow the panel to be placed apart from the floodlight.

The floodlight is controlled by a remote control which can activate the light and users can set up automatic activation according to their needs. Timer options are for three, five or eight hours, and the user can choose to have the floodlight working at 100% or 50% power.
