HT Instruments HT12 digitálny kliešťový multimeter CAT III 300V CAT II 600V 3400 Counts

Electricians and HVAC technicians rely on the HT Instruments HT12 clamp meter for quick current measurements without breaking the circuit. It measures AC current up to 200 A by clamping around a single conductor, and also handles AC/DC voltage to 600 V, resistance, capacitance, frequency, continuity and diode testing. The 3400-count LCD display offers clear readings, and the 25 mm jaw opening accommodates common cable sizes.
