6.3 Degree of emission

Materials have different degrees of emission, i.e. they produce different quantities of electromagnetic radiation. The degree of emission of the testo 845 is set at 0.95 ex-works. This is optimal for measurements of non-metals, plastics and food (paper, ceramics, plaster, wood, paints and lacquers).

Because of their low or inconsistent degrees of emission, bright metals and metal oxides have only limited suitability for IR measurements.

Apply emission-enhancing coatings such as paint or emission adhesive tape (Order No. 0554 0051) to the object to be measured. If this is not possible, measure with a contact thermometer.
