The Klein Tools MM6000 is a True RMS auto-ranging digital multimeter rated CAT IV 600V with IP20 ingress protection, designed for electricians and HVAC technicians. It measures AC/DC voltage up to 1000V, AC/DC current up to 10A, and resistance up to 5 MΩ. The large backlit display and 9.8-foot drop protection deliver reliability on demanding job sites. Low impedance mode reduces ghost voltage, and the µA setting supports flame sensor diagnostics. This product has been discontinued. Backed by Klein Tools' 1-year limited warranty.
Is the MM6000 still available?
No — the MM6000 has been discontinued. The MM720 is the current equivalent.
What was the MM6000?
A True RMS + LoZ HVAC/electrician multimeter at CAT IV 1000V with a 6000-count display — one of the higher-spec meters in the previous Klein lineup.
What replaced it?
The MM720 matches the True RMS + LoZ + 1000V + 6000-count platform with an updated reverse-contrast display.
