The Testo 810&nbsp;2in1 IR thermometer allows the simultaneous measurement of the air temperature and surface temperature of the object being measured - without contact. The infrared temperature measuring instrument automatically displays the temperature difference. This makes it particularly suitable for use in the heating, ventilation and air conditioning trade.&nbsp;

The testo 831&nbsp;2 Point IR thermometer allows you to carry out quick and precise temperature measurements of whole pallets of food and smaller products from a distance. Ideal for checking the temperature of incoming goods and for use in food production.&nbsp;
