Description

Precision Power Testing for Demanding Electrical Work – Built for Pros Who Need More Than Just Voltage

The Klein Tools CL900 Digital Clamp Meter is a rugged, auto-ranging TRMS tester designed for high-performance diagnostics in residential, commercial, and industrial environments. With the ability to measure up to 2000A AC/DC current and 1000V AC/DC voltage, this meter is ideal for troubleshooting large systems, motors, and panels. The integrated Low Impedance (LoZ) mode helps eliminate ghost voltages, while the Inrush Current capture mode ensures accurate startup readings. A built-in non-contact voltage tester (NCVT), backlit LCD, and CAT IV 600V safety rating make this meter a reliable companion for electricians and technicians working in low-light or high-risk environments. Whether you're testing continuity, frequency, capacitance, or diodes, the CL900 delivers accurate results with intuitive controls and durable construction.
