IT811 Digital Insulation Resistance Tester with LCD Display for Power Tools

Welcome to our shop!

Discover our digital insulation resistance tester, a brand new professional tool designed for precise and reliable measurements. It is perfectly suited for testing the insulation resistance of motors, cables, electromechanical equipment, telecommunications devices, and electrical installations.

This model features a large, backlit 64 x 44 mm LCD screen offering clear readings with a maximum display of 1999. It boasts a wide measuring range and an out-of-range indicator (a "1" is displayed on the leftmost digit when the range is exceeded). The data hold and test lock functions ensure stable and convenient operation.

To conserve battery power, the device automatically shuts off after approximately 15 minutes of inactivity. It operates on six 1.5V dry cell batteries (not included) and displays a low-voltage indicator when necessary.

Made of robust ABS, it can be used in environmental conditions from 0°C to 40°C and with a relative humidity of 30% to 85% RH.
