- 【Professional Insulation Resistance Tester – Quick and Easy to Use】: The M500 Megohmmeter is a professional insulation resistance tester designed for HVAC technicians, electricians, and maintenance engineers. It provides fast pass/fail insulation tests with a one-button operation, saving time on every compressor test, motor winding inspection, appliance diagnosis, panel board check, and relay control circuit troubleshooting. Compact, lightweight, and easy to use, this diagnostic tool eliminates guesswork and ensures reliable service results.
- 【Accurate 500V Measurement Range – Reliable Diagnostic Tool】: With a stable 500V DC output, the meter measures insulation resistance from 20 to 1000 megohms, providing accurate, reliable, and consistent readings for electric motors, hermetic refrigeration compressors, HVAC systems, control wiring, and industrial equipment. The wide range makes it a dependable diagnostic tool for insulation degradation, moisture intrusion, and heat-damaged windings, ensuring technicians and electricians can trust the results in both.
- 【Clear LED Zone Scale – Easy to Read and Customer Friendly】: The tri-color LED zone scale provides instant results: Red = Bad insulation (<20 MΩ), Yellow = Caution (40–100 MΩ), Green = Good (150–1000 MΩ), No Light = Excellent (>1000 MΩ). This clear display makes it simple to read insulation resistance even outdoors, and allows technicians to show customers the test results directly, building trust during HVAC and electrical service calls. Easy interpretation reduces mistakes and speeds up decision-making.
- 【Safety and Durability – Auto-Discharge and Rugged Build】: Built-in auto-discharge safety circuitry releases residual voltage after testing, protecting users during compressor tests, motor diagnostics, and panel board inspections. The rugged, impact-resistant housing with rubberized grip withstands tough jobsite conditions. Enhanced test leads with strong alligator clips provide secure contact and reduce the chance of breakage or false readings, addressing common concerns from field use. This durable design ensures long-term reliability for electricians and HVAC technicians.
- 【Portable, Convenient, and Cost-Effective Solution】: Weighing only 0.75 lb, the M500 is lightweight, compact, and portable, supplied with a soft carrying case for easy storage and transport. Powered by 2 × C batteries (Included), it is convenient for service trucks, HVAC field jobs, and industrial maintenance. Test leads store neatly in the case, keeping the diagnostic tool organized. As an affordable alternative to expensive Fluke or taut-band meggers, this product is widely praised as a great tool that works reliably for compressors, motors, wiring, and control circuits.
- 【Five-Year Warranty】: You don’t need to worry about the M500 Megohmmeter, failing within a few months. We offer a lifetime free replacement guarantee. If you encounter any issues during use, please feel free to contact us at any time. We promise to provide a satisfactory solution within 12 hours, ensuring a worry-free user experience.
