Insulation resistance tester 250 V-2500 V, megohmmeter 1 MΩ-200 GΩ, auto-ranging, 2000 counts, LCD screen, voltmeter 10 V to 600 V AC/DC, 100 data points stored

General Description

The digital resistance isolator is a multifunctional test instrument for measuring insulation resistance and AC/DC voltage, with advanced features such as absorption ratio, polarization index, and automatic discharge. It features a large, backlit digital display for high stability and reliability and can store up to 100 sets of data. The device requires no batteries and is powered by eight 1.5V AA batteries. Therefore, it is ideal for testing transformers, motors, cables, switches, and other electrical equipment, as well as insulation materials.
