HT Instruments JUPITER Digital Multimeter & RCD Tester, ISO Calibrated, CAT IV 600V / CAT III 690V, 6000 Counts, Bluetooth 1010680

Electrical installations demand precise verification of safety and performance. The HT Instruments JUPITER combines a full-featured digital multimeter with an RCD tester, enabling electricians and maintenance technicians to measure voltage, current, resistance, capacitance, frequency, loop impedance, and prospective fault current, and to verify RCD trip times and currents. With ISO calibration, it is ready for professional use in demanding environments.

Who is it for

Qualified electricians, electrical contractors, and maintenance personnel who need a single, reliable instrument for both general electrical measurements and RCD testing in residential, commercial, and industrial settings.
