About this item

MG500 he Sanwa MG500 is a robust, handheld digital insulation tester designed for reliable measurement of insulation resistance in electrical installations up to 600 V under CAT III. Housed in an IP54‑rated casing with a protective overmold, it presents readings on a large backlit 4,200‑count LCD augmented by a log‑type bargraph for intuitive analog‑style feedback. With auto‑ranging across four insulation ranges (4 MΩ–4 GΩ) and selectable test voltages of 125 V, 250 V, and 500 V DC, the MG500 automatically discharges capacitive circuits upon completion, ensuring user safety. Voltage, resistance, and insulation functions are seamlessly integrated: AC/DC volts to 600 V with auto‑detect, resistance continuity with buzzer and alarm indicator below 40 Ω, and a dedicated 40 Ω range offering short‑circuit currents ≥200 mA. Live‑circuit detection inhibits insulation tests above 30 V, triggering audible and visual alarms. Auto‑hold captures measurements upon release of the MEASURE button, while an auto‑power‑save mode preserves battery life after 10 minutes of inactivity. Built to withstand the rigors of industrial environments operating from 0 °C to 40 °C at up to 90 % RH it draws minimal current (7 mA on voltage range) from six AA cells, delivering hundreds of insulation tests per set. The MG500’s combination of safety features, analog‑style feedback, and comprehensive test functions makes it an essential tool for electricians and maintenance professionals.
