The KLEIN CL320 HVAC Digital Clamp Meter is an automatically ranging True Root Mean Squared (TRMS) tool designed specifically for HVAC professionals. It accurately measures AC current (400A), AC/DC voltage, resistance, frequency, capacitance, duty cycle, and continuity. Crucially for HVAC applications, it measures DC microamps for testing flame sensors and includes a K-Type thermocouple probe for temperature measurements.
The meter features a Non-Contact Voltage Tester (NCVT) integrated into the clamp jaw and a backlit LCD for low-light environments. It offers Data Hold, Max/Min functions, and an auto-power off feature to save battery. Built tough for the job site, it withstands a 6.6-foot (2 m) drop and carries a CAT III 600V safety rating. The kit includes a carrying case, test leads, thermocouple, and batteries.
