MEWOI-JF9300M 5KV High voltage insulation resistance tester with printer,touch screen,Megôhmetro digital de 5kV
The MEWOI-JF9300M is a smart, 5kV insulation tester and analyzer with Printer and Touch Screen.The measurement of insulation resistances up to 500GΩ, its advanced features allow to automatically measure both the Polarization Index and Dielectric Absorption Index, thus significantly simplifying testing of transformers.
This insulation tester is a portable, battery-powered equipment. Test voltage may be chosen from 500 V to 5 kV in 500V increments. High output current, short circuit current greater than 5mA.Due to its measurement principle (actual voltage and current readings) the accuracy of resistance measurement is not affected by any test voltage error.
The absorption ratio and polarization index are calculated automatically, and the data of 15 seconds, 1 minute and 10 minutes per minute are stored automatically for easy analysis.
The MEWOI-JF9300M is powered using a rechargeable battery and has an automatic charger that may be connected to 180 - 270V mains supply. The cabinet is strong and lightweight, easy to carry, impact-resistant and suitable to be used under severe weather conditions. Thus the megohmmeter supplies very reliable and accurate measurements both in laboratory and out in the field.
