The GT5307A 1000V Voltage Insulation Resistance Tester is a professional digital ohm meter and high tension megger designed for comprehensive insulation resistance testing. This advanced instrument utilizes a low-loss, high-change ratio inductive energy storage DC voltage converter to transform 9V input into 250V/1000V DC output, combined with a digital electric bridge for precise resistance measurement.
Ideal for insulation resistance testing requirements across various applications including motors, cables, electromechanical equipment, telecommunication systems, and power facilities. Features ergonomic two-handed operation with strap, backlight display, data hold function, and stable performance in a compact, professional design.
