Description
Klein Tools HVAC Digital Clamp Meter
400 Amp AC Auto-Ranging
This automatically ranging true root mean square (TRMS) digital clamp meter is ideal for HVAC work in residential and light-industrial zones (meets requirements for controlled electromatic environments). Use the clamp for AC currents, or the included test-leads for measuring AC/DC voltage, DC microamps, resistance, continuity, frequency, capacitance, and test diodes. A thermocouple probe is also available for measuring temperature.
A diode-test function helps you troubleshoot malfunctioning diodes, while the min/max feature can be utilized to understand the variability from average of an electrical property being measured.
Proudly Made in the U.S.A. ![]()
