Klein test and measurement covers the diagnostic spine of trade work: non-contact voltage testers for quick presence-of-voltage checks, multimeters for measured values, clamp meters for in-circuit current, and dedicated testers for receptacles, GFCIs and continuity. Match the CAT rating to the system you are testing.
Common questions
Which Klein meter do most electricians start with?
The MM400 or MM600 auto-ranging multimeter paired with an NCVT pen covers the large majority of residential and light-commercial work. Add a CL clamp meter such as the CL220 or CL390 when you start measuring load current without breaking the circuit.
What is the difference between an NCVT and a multimeter?
An NCVT detects an energized AC field without contact, giving a fast yes or no for safety checks. A multimeter measures actual voltage, current, resistance and continuity in contact with the conductor. Pros carry both, using the NCVT first and the meter to verify.
Are Klein meters CAT-rated?
Yes. Klein multimeters and clamp meters carry CAT III 600V, or CAT IV 600V and CAT III 1000V, depending on the model. Match the rating to where you are measuring: service entrance is CAT IV, branch circuits CAT III.
