Guangzhou Zhengneng Electronic Technology Co., Ltd.

1. Characteristics
Digital insulation resistance tester, also known as megohmmeter and high-voltage insulation resistance meter, is used for testing insulation resistance. This instrument has functions such as large-screen gray-white backlight display, data storage, data retrieval, alarm, automatic discharge, charging, automatic shutdown, etc. It also has the function of measuring DC voltage AC voltage absorption ratio and polarization index. The whole machine is beautiful, high-end, wide range, high resolution, easy to operate, easy to carry, accurate, reliable, stable performance, large output power and strong anti-interference ability.
And it has a shockproof, dustproof and moisture-proof structure to adapt to harsh working environments. It is commonly used and indispensable in telecommunications, electric power, meteorology, machine rooms, oil fields, mechanical and electrical installation and maintenance, and industrial enterprise departments that use electricity as industrial power or energy. meter. It is suitable for measuring the insulation resistance values of various insulating materials and transformers, motors, cables and electrical equipment.
The digital insulation resistance meter is composed of medium and large scale integrated circuits. This watch has high output power and multiple output voltage levels (one voltage level). Rated insulation test voltage range ~ insulation resistance measurement range.&;~&;. DC voltage measurement range~AC voltage measurement range~.
