Kyoritsu KEW 3127 High Voltage Insulation Tester
Karya Mandiri Techindo has a wide range of Kyoritsu products – search by type, or model, or filter by brand to find the one you are after. If you still can’t find it contact us..
Kyoritsu 3127 is a rugged 5kV tester capable of producing resistance measurements of up to 10TΩ.
Output voltages of 250 to 5000V can be programmed using a simple rotary dial, whilst an in-built electronic noise filter reduces electrical noise interference allowing for accurate and stable measurements. Test measurements can be logged in it’s internal memory for future analysis and live test data can even be viewed on a PC or Android device when using the “KEW SMART 3127” application which is available free of charge from the Google Play Store.
The Kyoritsu 3127 5kV insulation tester will conduct diagnostic insulation tests (IR, PI, DAR, DD, SV and Ramp – breakdown and burn modes) ensuring HV maintenance and commissioning specifications are met. Numerical test results are presented on a large back light display alongside a bar-graph indicator.
