The Klein Tools MM1000 is an auto-ranging digital multimeter rated CAT IV 600V with IP20 ingress protection designed for electricians. It measures AC/DC voltage up to 1000V, AC/DC current up to 10A, resistance, capacitance, frequency, duty-cycle, and temperature. The backlit display with analog bar graph supports diverse jobsite conditions, and 6.6-foot drop protection ensures durability. Max/Min/Relative reading and data hold functions aid diagnostics. This product has been discontinued. Backed by Klein Tools' 1-year limited warranty.
Is the MM1000 still available?
No — the MM1000 has been discontinued. The MM720 is its current equivalent.
What was the MM1000?
An electrician-focused multimeter rated for CAT IV 1000V — one of the earlier Klein meters to carry the high-voltage CAT IV rating, though it used average-sensing rather than True RMS.
What replaced it?
The MM720 (True RMS + LoZ, CAT IV 600V / CAT III 1000V) is the current 1000V electrician's multimeter, adding True RMS and ghost-voltage elimination.
