    Martindale DT175 Dual-Channel Thermometer

    The Martindale DT175 Dual-Channel Thermometer is a high-performance temperature measurement instrument that can work with type K thermocouples. It is capable of measuring temperature in a variety of media with a basic accuracy of ±0.3% + 1˚C and a resolution of 0.1˚C / 1˚C. It is supplied with two thermocouples which have measurement ranges of 0 to 260˚C.

    Differential measurement allows the user to see the difference between the input and output temperatures of various systems. Otherwise, the Martindale DT175 can check the real temperature from each probe and it is also possible to toggle between Celsius and Fahrenheit. The user has the option of min/max/average recording and performance is enhanced by the offset adjustment function. Results are shown on a backlit digital screen.

    A stand is integrated into the Martindale DT175 for additional practicality and using the thermometer is easy thanks to the clearly-labelled buttons. Supplied accessories include two type K thermocouples, a protective holster, batteries and an instruction manual.
