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

The Klein Tools A-CL445 HVAC Clamp Meter is a professional-grade digital clamp meter designed for HVAC and electrical diagnostics. It measures up to 600A AC (including inrush), supports 750V AC / 600V DC, and includes true RMS auto-ranging for accurate readings on variable loads. Integrated non-contact voltage detection and a dual display with backlight provide added safety and visibility.

With a K-type thermocouple input, it measures temperatures from -100°C to 1000°C. The meter also supports DC microamps, resistance, continuity, frequency, duty cycle, diodes and capacitance, making it ideal for HVAC, control, and general electrical work. Supplied with test leads, alligator clips, thermocouple, soft case and batteries.
