The mini surface thermometer from Testo provides you with the best equipment for carrying out surface temperature checks. Its particularly wide measuring tip makes it easy to place on a smooth surface. We recommend our silicon thermal paste (optional) for fast measurement results. This provides optimal thermal transference between the measuring tip and object being measured. Mini surface thermometer performance features The mini surface thermometer has a wide range of applications and can be used for the most varied methods of surface temperature measurements: e.g. for temperature checks in heating engineering, the sanitation sector, or air conditioning/refrigeration and ventilation technology. The diverse potential uses are not only down to its practical size (120 mm long probe shaft), but also its large measuring range. In fact, the mini surface thermometer allows you to measure temperatures from -50 to +300 °C. Your surface temperature measurement result is easy to read on the clear digital display. Choose between °C and °F for the unit displayed. Using the mini surface thermometer could hardly be any easier.
