Precise Insulation Testing, Ensure Electrical Safety：The M500 megohmmeter (compatible with Supco M500) measures insulation resistance up to 1000 megohms at 500V AC. Works for motors, transformers, HVAC systems，quickly detects defects. A must for pros/DIYers using hvac tools
Intuitive Display, Efficient Operation：Built-in resistance scale shows insulation status (Good/Normal/Risk) clearly. No complex analysis，judge equipment health fast, simplify tests. A top megger for Insulation Testing, ideal for hvac users
Durable Design, Tackle Harsh Environments：Double-sided ABS housing resists impacts/wear, endures collisions/friction for tough HVAC tasks. Cuts maintenance costs, long term worry free. Ideal for HVAC tools and megger testing
Portable & Easy Use, Flexible Storage：Comes with soft case for 6 inch leads & meter. Battery powered (2 “C” not included). Clear manual，do Insulation Testing anywhere. Convenient for on site work with hvac tools
