Features
Klein Tools CL380 is an automatically ranging true root mean squared (TRMS) digital clamp meter that measures AC/DC current via the clamp, AC/DC voltage, DC microamps, resistance, continuity, frequency, capacitance, and diodes via test leads, and temperature via a thermocouple probe. It includes a non-contact voltage tester integrated into the clamp, and features a high visibility, reverse contrast LCD display that optimizes viewability both in dark or bright ambient lighting.

Klein Tools is the result of one of those “happy accidents” that turn out to be revolutionary. Klein Tools famously got their start in 1857 when a linesman came to founder Matthias Klein to repair his broken pliers. Klein replaced the broken half and when the old half of the tool broke too, Klein forged a replacement for that, thus making the first Klein Linesman pliers. Since these humble beginnings, Klein Tools has grown and become one of the largest American made toolmakers and they’re a brand used by tradesmen, linesman and electricians all across America.
