High-Precision Insulation Resistance Measurement: The M500 megohmmeter delivers accurate insulation resistance testing up to 1000 megohms at 500V AC. Designed for professional use on motors, transformers, and so on, it reliably identifies insulation weaknesses to help maintain electrical safety
Clear Visual Rating System for Quick Assessment: Features an intuitive built-in resistance scale that clearly indicates insulation status as Red = Bad insulation (<20 MΩ), Yellow = Caution (40–100 MΩ), Green = Good (150–1000 MΩ), No Light = Excellent (>1000 MΩ). This allows for fast, informed decisions without complex interpretation
Robust Construction for Demanding Work Environments: Housed in a double-sided ABS case, engineered to perform reliably in challenging conditions, reducing long-term maintenance needs
Portable and Ready for On-Site Testing: Includes a protective soft case for organized storage of the meter and 22-inch test leads. Powered by two C-cell batteries (not included), this lightweight tool offers convenient portability and clear instructions for insulation testing wherever needed
Versatile Professional-Grade Testing Solution: Suited for a wide range of electrical inspections including motor windings, HVAC compressors, control panels, and relays
