The Klein Tools CL2100 is a 400A AC/DC True RMS auto-ranging clamp meter with temperature measurement via thermocouple, rated CAT III 600V. It measures AC/DC voltage, AC/DC current, resistance, capacitance, frequency, duty cycle, and temperature, and also tests diodes and continuity. Features include a backlit display with analog bar graph, non-contact voltage detection, and magnetic mount with lead storage. Suitable for electricians and HVAC technicians requiring comprehensive measurement capability. The CL2100 is no longer in production. Backed by Klein Tools' 1-year limited warranty.
Is the CL2100 still available?
No — the CL2100 has been discontinued. The CL490 is its current equivalent.
What was the CL2100?
A 400A AC/DC True RMS clamp meter with thermocouple temperature measurement — an HVAC-oriented instrument combining current and thermal sensing with True RMS accuracy.
What replaced it?
The CL490 (400A AC/DC True RMS, temperature, dual display) is the direct replacement, adding a dual display for simultaneous parameter readings.
