Details

The MT332 is a Clamp ground resistance tester, also known as loop resistance tester and is used to test ground resistance. This instrument uses a new black luxury screen design, the resistance current is displayed on the same screen, and it also has functions such as data storage, data review, alarm, and automatic shutdown. . The high grade of the MT247 is a reliable tester with a stable performance and has a wide measuring range, high resolution and accuracy, with strong anti-interference ability. The meter is housed in a shock-proof, dust-proof and moisture-proof structure. It is a common and indispensable instrument suitable for measuring grounding resistance of various telecommunications, electricity, meteorology, computer rooms, oil fields, electromechanical installation and maintenance, tower transmission lines, gas stations, factory grounding grids, lightning rods and industrial enterprises that use electricity as industrial power or energy. The MT332 is controlled by a microprocessor and can accurately detect ground resistance. It uses fast filtering techniques to minimize interference. Simultaneous data storage and data upload functions.
