GT5306A 1000V Voltage Insulation Resistance Tester Digital Ohm Meter high tension megger AC Voltage Insulation tester.
This instrument features a DC voltage converter with low loss, high variation ratio, and inductive energy storage, converting 9V voltage to 250V/1000V DC voltage. It utilizes digital electric bridge technology to measure insulation resistance and offers portability, wide measuring range, backlight display, and data holding capabilities. The instrument can also measure electric supply and features straps for convenient two-handed operation.
With its fashionable appearance and stable performance, it is suitable for measuring electrical machinery, cable, electromechanical equipment, telecom equipment, electric power facilities, and other insulation resistance applications.
