Dual Differential Thermometer

The UEI DTK2 Dual Differential Thermometer is a professional dual-input K-type thermometer designed for HVAC/R, refrigeration, heating, ventilation and service diagnostics. It allows technicians to measure two temperature points at the same time using dual K-type thermocouple inputs, with the ability to display T1, T2, or the differential reading T1 - T2. This makes it ideal for checking temperature split, supply and return air, pipe temperatures, coil performance and general heating or cooling system diagnostics.

The DTK2 offers a wide temperature measurement range of -328°F to 2498°F / -200°C to 1370°C, with selectable °F / °C units and a 0.1°F / 0.1°C resolution. It also includes Max/Min capture for T1 and T2, Data Hold, large LCD display, and automatic ice-point calibration for use with thermocouple probes.

Built for field use, the DTK2 features auto power off after 15 minutes, with the option to disable sleep mode, plus a magnetic mount for convenient hands-free use on equipment panels. It is powered by a 9V battery, with typical battery life of approximately 125 hours. The unit comes supplied with the meter, two ATT29A K-type bead probes, 9V battery, operation manual and pouch.
