Testo 810 Infrared Thermometer, -30°C Min, ±2 % Accuracy, °C Measurements

A pocket sized infrared temperature measuring instrument for non-contact measurement.
1-point laser measurement point marking and 6:1 optics, measure radiators, windows and air outlets amongst many more applications. The difference between air and surface temperature is automatically displayed, it features a settable emissivity and min. /max function. With a sleek design for quick access and easy storage, such as pockets, and a large illuminated display this is a handy laser thermometer, literally.

• Protective cap for storage, wrist strap and belt-holder
• 6:1 distance to spot
• -10 to +50 °C operating temperature range
• Hold-function, Min/Max/Dif
• Adjustable emissivity

IR thermometers are not harmful, they do not emit radiation, only measure it like a digital camera.

The majority of IR thermometers have a measurement error specification, which shows their best accuracy. The surface being measured can also affect accuracy. Reflective objects result in lower measurements than the actual temperature, whilst non-reflective surfaces give higher measurement. The emissivity of a surface is how effective it is at emitting energy as thermal radiation, as such some IR thermometers have adjustable emissivity settings.
Distance to spot ratio is also essential in providing accurate temperature measurements, if an infrared thermometer is too close to its target area, heat can build up in the device. This can give false readings or damage the temperature sensors, therefore it is essential to always follow a manufacturers guidelines.
