Klein Tools CL220-KLEIN Clamp Meter Ac Ncvt Temperature

Product Description

The KLEIN TOOLS CL220-KLEIN is a True RMS clamp meter designed for measuring AC current and non-contact voltage (NCVT) via clamp, along with AC/DC voltage, resistance, and continuity via test leads. A thermocouple input adds temperature measurement capability, covering a range of -40 degrees F to 1832 degrees F. The meter features automatic ranging True RMS technology, which improves accuracy on non-sinusoidal waveforms common in variable-speed drives and other modern loads. A backlit LCD supports readability in low-light conditions such as electrical panels and mechanical rooms. The housing is constructed from ABS material for durability in field use.

This clamp meter is suited for residential, commercial, and light industrial electrical work. Electricians and HVAC technicians use it for diagnosing circuits, verifying voltage levels up to 600 volts, checking continuity, and taking temperature readings with the included thermocouple. The NCVT function allows for fast, no-contact voltage detection before making contact with conductors, supporting safe work practices during troubleshooting and installation tasks.

Key Features

• True RMS measurement for accurate readings on non-sinusoidal waveforms
• Non-contact voltage detection (NCVT) via clamp for no-touch circuit verification
• AC/DC voltage, resistance, and continuity measurement via test leads
• Thermocouple temperature input with a range of -40 degrees F to 1832 degrees F
• Automatic ranging eliminates manual range selection
• Backlit LCD display for use in low-light environments
• ABS housing for field durability

Compatibility

Designed for use as a general-purpose clamp meter across residential, commercial, and light industrial electrical and HVAC applications where AC current, voltage, continuity, and temperature measurements are required.

Installation Notes

This instrument is intended for use by qualified electricians and HVAC technicians familiar with safe electrical measurement practices. Always verify the circuit voltage rating does not exceed 600 volts before taking measurements. De-energize circuits where possible before connecting test leads for resistance or continuity checks. Follow applicable NEC guidelines and local codes when working inside electrical panels or on live conductors.
