The advanced CL445 Clamp Meter (Cat. No. CL445) from Klein Tools features automatic ranging true root mean square (TRMS) for maximum accuracy.

Klein Tools Clamp MeterHighlights include:

  • Automatically ranging true root mean square (TRMS) digital clamp meter
  • Digital clamp measures 600A 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-Degrees Fahrenheit (-10 to 1000-Degrees Celsius)
  • Detect AC current with non-contact voltage tester integrated into the clamp jaw
  • Backlight LCD with dual V + A function allows simultaneous viewing of voltage and current measurements
  • Meter has a built-in worklight to illuminate in low light areas
  • Dedicated mode for capturing DC micro amp and inrush current

“Building tools that meet the specific needs of trade professionals is always a priority of our engineering team,” says Amy Hart, senior product manager at Klein Tools. “With the CL445 Clamp Meter, we have designed a meter that focuses on the functionality needed by HVAC technicians. Those functions include DC microamps to test flame sensors, K-type ports that allow a range of thermocouple types, and inrush current for testing furnace motors.”
