The Klein Tools MM1300 is an auto-ranging digital multimeter rated CAT IV 600V with IP20 ingress protection, tailored 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 via included thermocouple. A backlit display, analog bar graph, and 6.6-foot drop protection support demanding field use. Max/Min, data hold, and diode and continuity test functions are included. This product has been discontinued. Backed by Klein Tools' 1-year limited warranty.
Is the MM1300 still available?
No — the MM1300 has been discontinued. The MM720 covers the same spec territory.
What was the MM1300?
An electrician/HVAC-focused average-sensing multimeter rated for CAT IV 1000V — designed for dual electrical/HVAC use but without True RMS accuracy.
What replaced it?
The MM720 (True RMS + LoZ, 1000V) is the current equivalent for combined electrical and HVAC multimeter work.
