The HT Instruments HT65 is a CAT IV true-RMS digital multimeter rated for DC voltage measurement up to 1500 V. It uses TRMS conversion for accurate readings on both AC voltage and AC current, and combines a broad set of electrical measurement functions in a single handheld instrument carrying a CAT IV 600 V / CAT III 1000 V to-ground measurement category with double insulation.

A digital multimeter measures fundamental electrical quantities — voltage, current, resistance and related parameters — and presents the result on a numeric display. The HT65 extends that core role across a wide function set: DC and AC TRMS voltage, a low-impedance (LoZ) voltage mode, DC and AC current via transducer clamps, resistance and continuity, capacitance, frequency, duty cycle, diode test, and temperature with a Type K probe.

ValueTronics stocks and holds its own inventory in a 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, so the instruments we list are equipment we actually keep on hand.

Product Core & Specifications

Important: Measurement category: CAT IV 600 V – CAT III 1000 V to ground. Double insulation, pollution degree 2.

Important: DC and AC current measurements are performed with external transducer clamps; the 40 A and 400 A ranges require the HT4006 transducer, and accuracy marked (***) refers to the instrument plus clamp. The transducer clamp is not part of the instrument's own specifications.

Important: Temperature measurement requires a Type K thermocouple probe; the stated accuracy is referred to the instrument without the probe.

Important: Measurement category: CAT IV 600V – CAT III 1000V to ground. Maximum DC voltage input 1500V; maximum AC TRMS voltage input 1000V.
