Supco M500 Insulation Tester with Case vs M500 Megohmmeter Insulation Tester
Key Differences
Supco M500 (A) has a much larger review sample and established brand reputation with complaints about short leads and some breakage; oiuebxe M500 (B) lists a lower price tier, includes leads and case, and specifies operation at 500 V but has far fewer reviews and no explicit warranty info. Choose A if you want the model with broader user feedback and brand recognition; choose B if you prioritize a more affordable option that still offers the same 0–1000 MΩ range and 500 V operation
