Quad Input IP67 Digital Logging Thermometer

The UEI DT304 Quad Input IP67 Digital Logging Thermometer is a professional four-channel temperature logger designed for HVAC/R, refrigeration, industrial maintenance, food service, process monitoring and temperature-critical service work. With four thermocouple inputs, IP67 water/dustproof protection, and 9,999 memory position logging with USB software download, the DT304 is built for technicians who need to measure, compare and record multiple temperature points at the same time.

The DT304 accepts J, K, T and E type thermocouples, allowing it to suit a wide range of temperature testing applications. It can display T1/T2 or T3/T4, while also supporting dual differential temperature readings including T1-T2 and T3-T4. This makes it ideal for checking temperature split, refrigeration performance, supply and return air, pipe temperatures, heat exchanger performance and multi-point monitoring across equipment.

The meter includes a large backlit multi-parameter display, Min/Max/Avg, Data Hold, logging interval control, USB data transfer, and convenient probe storage. Its rugged IP67-rated housing makes it suitable for demanding work environments where dust, moisture and jobsite conditions are a concern.
