The Klein CL445 HVAC clamp meter is built for HVAC professionals who demand accuracy, reliability, and versatility in a single tool. With its auto-ranging true RMS technology, this digital clamp meter ensures precise measurements even in noisy or fluctuating electrical environments. It measures up to 600A AC current, including inrush current, while the test leads provide detailed diagnostics for AC/DC voltage (up to 750V/600V), DC microamps, resistance, continuity, frequency, duty cycle, capacitance, and diode testing. Whether you're checking flame sensors, inspecting motor startup currents, or troubleshooting complex systems, this clamp meter has the features you need to work smarter and faster.
Designed with real-world job conditions in mind, the CL445 includes a K-Type thermocouple for measuring temperatures from -148°F to 1832°F (-100°C to 1000°C)—ideal for HVAC systems operating across a wide thermal range. The integrated non-contact voltage tester makes quick work of AC detection, while the backlit LCD with dual voltage and current display and built-in worklight ensures visibility in dark or cramped spaces. Rated CAT IV 600V and CAT III 750V with double insulation, this meter is built for safety in demanding environments.
Everything you need is included: right-angle test leads, push-on alligator clips, thermocouple, storage pouch, batteries, and instructions—ready to go right out of the box. For added convenience, it’s compatible with Klein’s magnetic hanger (sold separately) for hands-free use. Whether you're diagnosing, repairing, or installing, the CL445 gives you confidence with every measurement.
