GW Instek GPT-9803

Instek GPT-9803 Hi-Pot Tester – AC/DC Withstanding Voltage & Insulation Resistance Tester (200VA).

The Instek GPT-9803 is a high-performance AC/DC Withstanding Voltage (Hipot) and Insulation Resistance (IR) Tester designed to meet IEC, EN, UL, CSA, and other electrical safety requirements. With a 200 VA output power and precise control across AC Hipot, DC Hipot, and Insulation Resistance testing, this instrument is essential for manufacturers, compliance labs, and industrial technicians performing routine or production-line electrical safety testing.

Built with a True RMS current measurement, high-resolution voltage/current control, and PWM amplification, the GPT-9803 ensures safe, efficient, and accurate dielectric withstand testing. The intuitive 240×64 ice-blue LCD, quick-access function keys, manual/auto modes, and safety interlock mechanisms make it ideal for demanding QA environments.
