The Testo 845 is a compact infrared thermometer with switch optics for the non-contact measurement of surface temperatures. The switchable optics for far-field and close focus measurements make it possible to measure at short as well as at greater distances.
Measurements in the farfield are taken at an optical resolution of 75:1. This allows surface temperatures to be measured accurately even at greater distances to the measurement object.
For measurements at a short distance to the measurement object, the close focus optics offer a measurement point diameter of only 1 mm at a distance of 70 mm. T
