The Klein Tools MM5000 is a True RMS auto-ranging digital multimeter rated CAT IV 600V with IP40 ingress protection, designed for professional electricians. It measures AC/DC voltage up to 1000V, AC/DC current up to 10A, and offers ±0.3% basic DC accuracy. Low impedance mode reduces ghost voltage readings. The meter is built to withstand a 9.8-foot drop with double insulation and a raised rubber molding boot for display protection. Features include data hold, auto hold, range hold, MAX/MIN, and microamps setting. Made in USA. This product has been discontinued. Backed by Klein Tools' 5-year warranty.
Is the MM5000 still available?
No — the MM5000 has been discontinued. The MM720 is the closest current equivalent.
What was the MM5000 known for?
The MM5000 was a True RMS + LoZ multimeter rated CAT IV 1000V that carried a 5-year warranty — longer than the standard 1-year limited warranty on current Klein meters. It was positioned as a long-term investment for professional electricians.
What replaced it?
The MM720 matches the True RMS + LoZ + 1000V platform but carries the standard 1-year limited warranty rather than the MM5000's extended 5-year coverage.
