The Klein Tools CL2500 is a 1000A AC/DC True RMS auto-ranging clamp meter rated CAT IV 600V with IP42 protection, designed for high-current industrial and utility applications. The wide 1.97-inch jaw accommodates large conductors and conduit bundles. It measures AC and DC current and voltage, resistance, capacitance, frequency, duty cycle, and includes non-contact voltage detection. A backlit 6000-count LCD and analog bar graph aid readability. Magnetic mount enables hands-free positioning. Drop-rated to 3.3 feet. Well-suited for industrial maintenance and power distribution work. Covered by Klein Tools' 1-year limited warranty.
Is the CL2500 still available?
No — the CL2500 has been discontinued. The CL910 is the closest current high-capacity model.
What was the CL2500?
A 1000A AC/DC True RMS clamp meter with a built-in worklight, rated CAT IV 600V — positioned between standard 600A meters and the specialized flexible 3000A CL150 for large commercial installations.
What replaced it?
The CL910 (2000A AC/DC True RMS, worklight, LoZ, temperature, 2.0-inch jaw) is the current high-capacity option. It doubles the ampere capacity and adds LoZ and temperature measurement.
