The Testo 845 IR thermometer enables the accurate measurement of surface temperatures with smallest diameters at short and long distances through the use of switchable far-field and close focus optics. A cross laser marks the measurement point exactly and, at a distance of 1.2 metres from the object, the measurement point diameter is only 16 mm whilst at 70mm, the measurement point diameter is only 1 mm.
