Description

USA Lab Professional Digital Thermometer | Dual-Channel Thermocouple Temperature Meter

The USA Lab Professional Digital Thermometer is a versatile dual-channel thermocouple temperature meter designed for laboratory, industrial, HVAC, processing, and general temperature measurement applications. Supporting K, J, T, E, N, R, and S type thermocouples, it provides flexible temperature measurement across a broad range of low- and high-temperature processes with one reusable handheld instrument.

The dual-input design displays T1 and T2 simultaneously and includes T1-T2 differential temperature measurement for quickly comparing two temperature points. This makes the thermometer well suited for heat exchanger testing, supply and return temperature comparisons, HVAC diagnostics, laboratory processes, furnaces, cryogenic measurement, liquid monitoring, and surface temperature testing when used with a compatible thermocouple probe.

For convenient day-to-day operation, the USA Lab Professional Digital Thermometer features a backlit LCD display, data hold, MAX/MIN/AVG measurement, automatic power-off, and selectable thermocouple compatibility. Two K-type thermocouples and three AAA batteries are included so the thermometer is ready for general-purpose temperature measurement out of the box. For accurate measurements, allow the probe temperature to stabilize before recording a reading.

7 Thermocouple Types Dual-Channel T1/T2 T1-T2 Differential Backlit Digital Display
