§ FAQ

Is the MM500 still available?

No — the MM500 has been discontinued.

What was the MM500 known for?

The MM500 was an auto-ranging average-sensing multimeter rated for 750V AC and with an IP67 waterproof rating — making it the most environmentally protected meter in Klein's previous lineup at that tier.

What current model is closest?

The MM720 (True RMS, LoZ, 1000V) is the current premium multimeter but does not match the MM500's IP67 waterproofing. If full waterproofing is essential, verify current model ratings before purchasing.
