Klein Tools CL445 Clamp Meter is an advanced HVAC clamp meter with automatically ranging true root mean square (TRMS) for maximum accuracy. The meter measures AC current, inrush current, AC/DC voltage, DC microamps, resistance, continuity, frequency, capacitance, temperature, diodes, and more. This Digital Clamp Meter can simultaneously measure current and voltage, has a built-in worklight and comes with right-angle input test leads, push-on alligator clips, K-Type thermocouple, storage pouch, instructional manual, and 3 x AAA batteries. CL445 HVAC Clamp Meter is an automatically ranging true root mean square (TRMS) digital clamp meter. Digital clamp measures 600 A AC current and inrush current. Test leads measure 750V AC/600V DC voltage, DC micro amp, resistance, continuity, frequency, duty-cycle, capacitance, and diode tests. K-Type thermocouple port for measuring temperature from -148 to 1832-Degree Fahrenheit (-100 to 1000-Degree Celsius). Detect AC current with non-contact voltage tester integrated into the clamp jaw. Backlit LCD with dual V + A function allows simultaneous viewing of voltage and current measurements. Dedicated mode for capturing DC micro amp and inrush current. Meter has a built-in worklight to illuminate in low light areas. CAT IV 600V, CAT III 750V, Class 2, Double insulation safety rating. Includes right-angle input test leads, push-on alligator clips, K-type thermocouple, storage pouch, instruction manual, and 3 x AAA batteries. Can be used with Magnetic Hanger (Cat. No. 69417, sold separately) for hands free operation.
