HT3025 Insulation resistance meter (Megohmmeter 2500V)

I. Product Introduction

HT3025 digital insulation resistance meter, also name megohmmeter, high voltage insulation resistance tester, is used for insulation resistance test. This instrument has a large LCD screen gray backlit display, data storage, data review, alarm, automatic shutdown and other functions. At the same time, it also has the function of measuring absorption ratio and polarization index of AC voltage and DC voltage. The machine is beautiful and upscale, has a wide range, high resolution, convenient operation, easy to carry, accurate, reliable, stable performance, strong anti-interference ability.

HT3025 also has a shockproof, dustproof, moisture-proof structure, and adapts to the harsh working environment. It is a commonly used and indispensable instrument for electric power, post and telecommunications, communications, electromechanical installation and maintenance, and industrial enterprises that use electricity as industrial power or energy. It is suitable for measuring the resistance value of various insulating materials and the insulation resistance of transformers, motors, cables and electrical equipment.

HT3025 digital insulation resistance meter is composed of medium and large scale integrated circuits. The output power of the watch is large, and the output voltage level is more (has 5 voltage levels). Rated insulation test voltage range 100 ~ 2500V insulation resistance measurement range 0.01MΩ ~ 200GΩ. DC voltage measurement range 0~1000V AC voltage measurement range 0~750V
