The Klein Tools CL100 is a 600A AC clamp meter with a 1.0-inch jaw opening and 2000-count display, rated CAT III 600V. It measures AC current up to 600A, AC and DC voltage up to 600V, and resistance up to 20MΩ, and also performs diode and continuity tests. Features include a backlit display, integrated work light, data hold, and audible continuity buzzer. Designed for electricians performing high-current AC measurements on larger conductors and service panels. The CL100 is no longer in production. Backed by Klein Tools' 1-year limited warranty.
Is the CL100 still available?
No — the CL100 has been discontinued. The CL710 is the current 600A clamp meter in the Klein Tools lineup, adding True RMS measurement, Low Impedance (LoZ) mode, and a 1000V range.
What was the CL100 known for?
The CL100 was a 600A AC clamp meter with a built-in worklight rated CAT III 600V. It used average-sensing measurement rather than True RMS, which is accurate for pure sine-wave loads but less accurate on motors, VFDs, and other non-linear loads.
What current model should I consider instead?
The CL710 (600A, True RMS, LoZ, 1000V) or CL810 (adds worklight and temperature) are the appropriate current-generation replacements.
