Product Introduction
ND2501D Digital Insulation Resistance Tester, also known as a megohmmeter or high-voltage insulation resistance meter, is used for insulation resistance testing. This instrument features a large-screen LCD with gray-white backlight, data storage, data review, alarm, automatic discharge, charging, automatic shutdown, and more. It also includes functions for measuring DC voltage, AC voltage, absorption ratio, and polarization index. The unit is aesthetically pleasing and high-end, with a wide range, high resolution, easy operation, portability, accuracy, reliability, stable performance, high output power, and strong anti-interference capability. ND2501D is designed with shockproof, dustproof, and moisture-resistant construction, making it suitable for harsh working environments. It is an essential and commonly used instrument in telecommunications, power, meteorology, computer rooms, oil fields, electromechanical installation and maintenance, and industrial enterprises that use electricity as an industrial power source or energy. It is suitable for measuring the insulation resistance values of various insulating materials, transformers, motors, cables, and electrical equipment.
Product Features
ND2501D Digital Insulation Resistance Meter is composed of medium and large-scale integrated circuits. This meter offers high output power and multiple output voltage levels (6 voltage levels). The rated insulation test voltage range is 250V to 5kV, and the insulation resistance measurement range is 0.01MΩ to 2000GΩ. The DC voltage measurement range is 0 to 1000V, and the AC voltage measurement range is 0 to 750V.
