The Klein Tools CL390 is a versatile AC/DC digital clamp meter designed for electricians, offering precise and reliable measurements. Featuring automatically ranging true root mean squared (TRMS) technology, this meter measures AC/DC current and NCVT via the clamp, as well as AC/DC voltage, DC microamps, resistance, continuity, frequency, capacitance, and diodes via test leads.

It also measures temperature using a K-type thermocouple probe. The high-visibility reverse contrast LCD display ensures clear readings in all lighting conditions. Built to withstand a 6.6' drop, it includes a carrying case, test leads with safety caps, a thermocouple, instructions, and 3 x AAA batteries.
