Description Testo 810 IR thermometer measures the temperature on two channels. On the one hand, being an infrared thermometer it can take non-contact surface temperature measurements of the object being measured; on the other hand, it can measure the air temperature using its additionally integrated NTC sensor. The IR thermometer displays the temperature difference directly on the illuminated display. Functions and applications of the testo 810 IR thermometer The testo 810 IR thermometer is extremely well suited to use in heating, ventilation and air conditioning technology. At the touch of a button, you can measure the surface temperature of radiators, air vents, or windows and compare these to the air temperature. The compact size of the infrared thermometer makes it easy to store in your pocket and immediately accessible for taking measurements. When measuring surface temperatures, you can mark the required spot with the integrated 1 point laser to achieve a specific measurement. The 6:1 optics of the infrared temperature measuring instrument is primarily suitable for measurements at closer to medium distances. The IR thermometer emission level can also be individually set. This allows you to adjust it to the respective material properties of the surface being measured, as well as achieve the best measurement results. The integrated air temperature sensor is also highly reliable: this is an NTC temperature sensor which measures the air temperature with utmost accuracy. Other practical features of the IR thermometer are the min./max. display and the hold function (to record measuring values). A protective cap and belt pouch (included in scope of delivery) add to the safety of the infrared thermometer. Delivery Scope Testo 810 IR thermometer with integrated NTC temperature sensor, including protective cap, calibration protocol, belt pouch, and batteries.
