The Klein Tools MM2300 is a True RMS auto-ranging digital multimeter rated CAT IV 600V with IP20 ingress protection for electricians and HVAC technicians. It measures AC/DC voltage up to 1000V, AC/DC current up to 10A, resistance, capacitance, frequency, duty-cycle, and temperature. Low impedance mode reduces ghost voltage readings. The backlit display with analog bar graph and 6.6-foot drop protection suit demanding job-site conditions. This product has been discontinued. Backed by Klein Tools' 1-year limited warranty.
Is the MM2300 still available?
No — the MM2300 has been discontinued. The MM720 is its current equivalent.
What was the MM2300?
A True RMS + LoZ HVAC/electrician multimeter at CAT IV 1000V — essentially the same platform as the MM2000 in Klein's previous generation.
What replaced it?
The MM720 (True RMS + LoZ, 1000V) is the current replacement.
