The Testo 810 infrared thermometer makes not only accurate, non-contact surface temperature readings but also ambient air temperature readings... simultaneously. Having one instrument capable of making both surface and ambient temperature readings opens a range of applications for users, such as comparing the surface temperature of a radiator to the air temperature in the room as a way to gauge the efficiency of a heating system.
The Testo 810 has an infrared measuring range of -30 to +300 °C (-22° to 572°F) with an accuracy of ±2.0°C and an air temperature range of -10 to +50 °C (14° to 122°F) with an accuracy of ±0.5°C. Emissivity is fixed at 0.95 and the distance-to-spot ratio is 6:1. A built-in laser pointer helps aiming. The meter also displays the difference between air and surface temperature. Other features of the Testo 810 include a hold function, min/max values, adjustable emissivity and display illumination.
The Testo 810 comes with protective cap for safe storage. The meter ships complete with wrist strap and belt holder.
