VC60B Digital Insulation Resistance Tester 250V/500V/1000V Megohmmeter, 0.1MΩ2GΩ IR Measurement, AC Voltage Multimeter

🔹 Accurate Insulation Resistance Testing Supports 250V, 500V, and 1000V DC test voltages to measure insulation resistance from 0.1MΩ to 2GΩ with ±4% accuracy. Displays specific resistance values, not just range indications. 🔹 2-in-1 Megohmmeter & Multimeter Combines insulation resistance testing with a 1999-count multimeter for AC voltage measurement up to 750V (±1.0%). Also includes continuity test with audible buzzer for quick diagnostics. 🔹 Enhanced Safety Features Built-in high-voltage and short-circuit buzzer alarms, plus anti-high voltage protection circuitry. Ideal for testing floor heating cables, thermostats, motor windings, and other electrical insulation scenarios. 🔹 Fast Sampling & Data Hold Measures approximately 3 times per second for fast, responsive readings. Includes data hold function for recording values easily (Note: not available during insulation resistance testing). 🔹 Easy to Read, Built for the Field Equipped with a large 3.5" HD backlit LCD for clear visibility in low light. Compact and reliable – perfect for electricians, HVAC techs, or industrial maintenance checks.
