Instrument advantages
With a temperature measurement accuracy of ± 0.75°C and a reaction time of up to 100 ms, the testo 845 infrared thermometer enables you to achieve fast and reliable temperature measurements. The telephoto measurement function can measure the temperature of the object to be measured at a great distance, and objects as small as 16 mm in diameter can be accurately measured at a measuring distance of 1.2 m. Cross laser aiming assists in pinpointing the measurement location.
If the object to be measured is very small, a close-focus measurement can be used, which can measure the object as small as 1mm in diameter at 70mm, and the two-point laser sight assists in positioning. When it's time to switch from a telephoto measurement to a close-focus measurement, simply flip the switch on the instrument to the appropriate position.
In addition, the emissivity of the object can be determined with the help of an optional temperature probe, which enables more accurate measurement of the surface temperature.
