Insulation Resistance Tester -- This instrument applies automatic voltage release function, with high stability and reliability, features maximum 2000 counts, 100 groups of data storage, and 1MΩ-200GΩ insulation resistance measuring range.
AC/ DC Voltage Measuring -- Rated output voltage is variable, easy to switch between 250V/ 500V/ 1000V/ 2000V/ 2500V through the up/ down button.
Solve Practical Problems -- It is suitable for measuring the insulation resistance of various electrical equipments and insulating materials such as transformers, motors, cables, switches, electrical appliances, etc.
More Accurate Results -- Insulator is sensitive to temperature and humidity changes, and interference current when you start measuring will also affect the results.
Safe Operation, Portability -- High voltage indication to remind you of safe operation; low battery indication to remind you of replacing batteries in time.
