The Klein Tools MM6000N is a NIST-certified True RMS auto-ranging digital multimeter rated CAT IV 600V with IP20 ingress protection. It measures AC/DC voltage up to 1000V, AC/DC current up to 10A, and temperature from -58 to 1832°F. The 6000-count backlit display, ±0.2% DC accuracy, and 9.8-foot drop rating reflect professional-grade build quality. Low impedance mode reduces ghost voltage. NIST calibration certification is included for applications requiring traceable measurements. This product has been discontinued. Backed by Klein Tools' 5-year warranty.
Is the MM6000N still available?
No — the MM6000N has been discontinued. There is no current NIST-certified equivalent in Klein's active multimeter lineup.
What was the MM6000N?
The MM6000 HVAC/electrician True RMS + LoZ 1000V platform with an included NIST-traceable calibration certificate — the highest-spec NIST-documented multimeter in Klein's previous generation.
What current model is closest?
The MM720 is the closest active meter by spec. For NIST-traceable calibration, third-party calibration services for the MM720 are the current option.
