Digital Clamp Meter, Auto-Ranging 400 Amp AC, AC/DC Voltage, Resistance, Continuity, Non-Contact Voltage Tester Detection
Klein Tools CL120 Clamp Meter is an automatically ranging digital clamp-meter that measures AC current and NCVT via the clamp, and AC/DC voltage, resistance and continuity via test-leads. Klein Tools’ Test and Measurement product line was exclusively designed from the ground up by electricians for electricians. Years of field research, combined with extensive input from electricians across America, inspired the development of meters and electrical testers loaded with time-saving features.
