CL445 HVAC CLAMP METER

Klein Tools CL445 is an advanced HVAC clamp meter with

auto-ranging true root mean square (TRMS) for maximum accuracy.

The meter measures AC current and inrush via the clamp, AC/DC voltage,

DC microamps, resistance, continuity, frequency, capacitance, and tests

diodes via test-leads, and temperature via a thermocouple probe. High

visibility backlit LCD has V+A function to simultaneously monitor voltage

and current.
