The Martindale DT75 is a high quality, dual-input thermometer with temperature difference capability. The two K-Type inputs can accept a wide range of different probes and the thermometer can measure input and output temperature, as well as temperature differentials through boilers and radiators etc.

Temperature readings can be switched between C and F, with either a 1 or 0.1 resolution. Hold and maximum buttons enable the freezing of the current value, or for the maximum reading to be stored.

The Martindale DT75 is supplied with 2 x bead type probes, protective holster, battery and manual. This is also available in a thermometry kit, see the Martindale Thermo kit for more details.
