Description

Precision Meets Durability – Built by Electricians, for Electricians

The Klein Tools CL800 Digital Clamp Meter is a professional-grade electrical tester designed to deliver accurate diagnostics in demanding environments. Featuring True RMS auto-ranging technology, this meter measures AC/DC voltage and current up to 1000V and 600A, plus resistance, continuity, frequency, capacitance, and diode testing via test leads. The integrated thermocouple probe adds temperature measurement capability, while the Low Impedance (LoZ) mode helps eliminate ghost voltages for safer, more reliable readings. With a rugged build rated for CAT IV 600V and CAT III 1000V, drop-tested to 6.6 feet, and equipped with a 6000-count backlit LCD, the CL800 is ready for residential, commercial, and light-industrial applications.
