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. Clamp meter measures AC current and NCVT via clamp and AC/DC voltage, resistance and continuity via test-leads Non-contact voltage tester integrated into the clamp jaw Backlit LCD for ease of viewing in low light Auto-ranging measurements Test lead holder on side of clamp and optional magnetic hanger for meter (cat no 69445 or 69417) for hands-free operation
