The HT322 is a CAT IV digital multimeter with temperature measurements manufactured by HT Italia. It is a handheld 3½-digit instrument with a 1999-count maximum reading, automatic polarity indication, and a double-insulated enclosure that combines standard multimeter functions with Type K thermocouple temperature measurement in a single package.
A digital multimeter is a general-purpose electrical measurement instrument that reads voltage, resistance, and related parameters on a single display. The HT322 measures DC and AC voltage, resistance, and performs diode and continuity testing, and adds a dedicated temperature function that reads contact temperature through a Type K thermocouple probe.
ValueTronics stocks and holds its own inventory in a 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois.
