The Klein Tools MM5000N is a NIST-certified True RMS auto-ranging digital multimeter rated CAT IV 600V with IP40 ingress protection. It measures AC/DC voltage up to 1000V and provides ±0.3% basic DC accuracy. Low impedance mode eliminates ghost voltage, and the microamps setting suits flame sensor testing. The 4000-count backlit display and 9.8-foot drop rating reflect professional-grade durability. NIST calibration documentation supports compliance-critical applications. Made in USA. This product has been discontinued. Backed by Klein Tools' 5-year warranty.
Is the MM5000N still available?
No — the MM5000N has been discontinued. There is no current NIST-certified equivalent in Klein's active multimeter lineup.
What was the MM5000N?
The MM5000 platform with an included NIST-traceable calibration certificate — required for calibration-documented maintenance programs, ISO-certified facilities, and any work where measurement traceability must be documented.
What current model is closest?
The MM720 is the closest active meter by spec (True RMS + LoZ + 1000V), but does not include a NIST certificate. For NIST-traceable instruments, third-party calibration of the MM720 is the current path.
