Hioki clamp meters are best in class handheld current and voltage meters for safely and accurately measuring power lines. The CM3286-50 clamp on power meter can measure voltage, current, power, power factor, phase angle, reactive power or frequency, as well as detect phase sequence on live lines at any desired point of a single-phase circuit or three-phase circuit.
CAT IV 600 V, CAT III 1000 V
