The KD50A series digital insulation resistance tester, also known as a megohmmeter or high-voltage insulation resistance meter, is used for testing insulation resistance. This instrument has functions such as large screen LCD gray white backlight display, data storage, data retrieval, alarm, automatic discharge, charging, and automatic shutdown. It also has the function of measuring the absorption ratio and polarization index of DC voltage and AC voltage. The whole machine is beautiful, with a wide range, high resolution, easy operation, convenient portability, accuracy, reliability, stable performance, high output power, and strong anti-interference ability.
 
The KD50A series digital insulation resistance tester has shockproof, dust-proof, and moisture-proof structures, making it suitable for harsh working environments.

The KD50A series digital insulation resistance tester consists of medium to large-scale integrated circuits. This table has a high output power and multiple output voltage levels (with 6 voltage levels). The rated insulation test voltage range is 100V~15kV (the output voltage is determined according to the model), and it also has a step adjustment voltage function to output multiple different voltage levels (such as the 15kV model can generate voltage levels such as 12KV, which has a wider range of use). The insulation resistance measurement range is 0.01M Ω~50T Ω (the measurement range is determined according to the model); DC voltage measurement range 0-1000V; AC voltage measurement range: 0-750V; DC current measurement range: 0.01nA-6mA; The capacitance measurement range is 10nF to 50uF.
