ES3045 Megohm Insulation Resistance Tester 5kV/10KV/15KV 10/35/50TΩ Digital Megohmmeters For Transformer/Motors Electrical Equipment Installation Maintenance

Ⅰ. Characteristic

ES3045 series digital insulation resistance tester, also known as megohmmeter, high voltage insulation resistance meter, is used for insulation resistance test. The instrument has large-screen LCD gray and white backlight display, data storage, data access, alarm, automatic discharge, charging, automatic shutdown and other functions. At the same time, it also has the function of measuring the absorption ratio of DC voltage and AC voltage and polarization index. The whole machine is beautiful and high-grade, with a wide range, high resolution, convenient operation, convenient carrying, accurate, reliable, stable performance, large output power, and strong anti-interference ability.

ES3045 series digital insulation resistance tester has a shock-proof, dust-proof and moisture-proof structure, and is suitable for harsh working environments. And an essential instrument. It is suitable for measuring the insulation resistance value of various insulating materials and transformers, motors, cables and electrical equipment.

ES3045 series digital insulation resistance tester consists of medium and large scale integrated circuits. This watch has large output power and many output voltage levels (there are 6 voltage levels). The rated insulation test voltage range is 100V ~ 15kV (the output voltage is determined according to the model), and it has a step-by-step voltage adjustment function to output a variety of different voltage levels (such as 15kV models can generate 12KV and other voltage levels, and the use range is wider), insulation The resistance measurement range is 0.01MΩ~50TΩ (determine the measurement range according to the model); the DC voltage measurement range is 0~1000V; the AC voltage measurement range is 0~750V; the DC current measurement range is 0.01nA~6mA; the capacitance measurement range is 10nF~50uF.
