Description
Kewtech KEW3125A High Voltage (5kV) Digital Insulation Tester
The Kewtech KEW3125A High Voltage (5kV) Digital Insulation Tester is designed for use on high voltage systems and allows measurements of insulation resistance.
Featuring four different test voltages of 500, 1000, 2500 and 5000V, the KEW3125 can carry out insulation resistance measurements up to a high threshold of 1000GΩ. The large-size screen on the front of the tester displays both a full testing value and also includes a bargraph which shows the test voltage currently being used. Also included is a rotary dial for selecting the applicable test voltage and a test initiation button.
This insulation tester also comes with memory for polar index measurements, output voltage monitor, a timer measurement function and several other useful additional functions.
