Insulation Resistance Tester Digital Meter Resistance Voltage Polarization Index DAR Measuring Meter LCD Display with Backlight

Features:
Preferred Mateiral: The cover is made of ABS insulation material, shockproof and can provide a long service time.
LCD screen with backlight design, you can press the button to turn on or turn off the backlight according to your needs, so you can see the testing data clear even at night.
100 Group Data Storage: After measuring the insulation resistance value, press HOLD button to keep the data first, and the screen will appear HOLD symbol, and then press READ button to save the data.
Absorption Ratio (DAR): Determine whether the equipment is affected by the dampness of the insulation resistance measurement Instrument programming defaults for calculating DAR with insulation resistance values at 15 seconds and 60 seconds.
Polarization Index (PI): PI measurement is used to identify the aging of insulation quality. The insulation resistance value at 1 and 10 minutes is used to calculate PI.
Wide Applications: This tool is suitable for measuring insulation resistance of transformers, motors, cables, switches, electrical appliances and other electrical equipment and insulation materials. Suitable for various electrical equipment maintenance, repairs, test and verification.
