TRIO  Test & Measurement supplies the Extech 380395, a new line of powerful, accurate and affordable 5KV insulation resistance testers that provide four insulation resistance test ranges.  

The insulation resistance test ranges include 500V, 1000V, 2500V and 5000V.  Extech’s 5KV insulation resistance testers also offer continuity, AC/DC voltage, polarisation index and dielectric absorption ratio measurements.  

Extech 380395 insulation resistance testers are designed to offer insulation resistance measurements up to 60GΩ.  

A large easy-to-read 6000-count display is also incorporated into the device with backlight and bargraph. The Data Hold feature freezes the reading on the display. The discharge status can be monitored in real-time using the voltage bargraph.
