        Klein Tools A-CL445 | HVAC Clamp Meter AC/DC | 600A

        The Klein Tools A-CL445 HVAC Clamp Meter is an essential tool for electricians, offering precise measurements and a range of advanced features. This automatically ranging true root mean square (TRMS) digital clamp meter accurately measures 600A AC current, inrush current, AC/DC voltage, DC microamps, resistance, continuity, frequency, duty cycle, capacitance, and diodes. The integrated K-Type thermocouple port measures temperatures from -148 to 1832 degrees Fahrenheit (-100 to 1000 degrees Celsius), making it versatile for various HVAC applications.

        The clamp meter includes a non-contact voltage tester integrated into the clamp jaw to detect AC current. The backlit LCD with dual V + A function allows simultaneous viewing of voltage and current measurements, enhancing usability in low-light conditions with its built-in work light. The device is safety rated CAT IV 600V, CAT III 750V, Class 2, with double insulation, ensuring reliable and safe operation.
