Non-contact infrared temperature measurement is...
...ideal for measuring the surface temperatures of:
a) Poor thermal conductors such as ceramic, plastic, rubber, wood, paper, wallpaper, plaster, textiles, organic materials, food.
The measuring instrument measures without any retroactive effect, i.e. without any influence on the meas-urement object. The IR radiation of the measurement object is therefore always at the same speed, irrespec-tive of thermal conductance.

b) Materials with a high emission level, e.g. lacquer, paints, glass, minerals, tiles, stone, tar and all non-metallic materials. In this case, an emission level setting of 0.95 is usually correct. Errors due to external radiation reflected on the surface are only slight.
c) Moving parts (provided that the material has a high emission level or a material with a defined emission level can be applied) e.g. running paper webs, rotating tyres or oxi-dised steel parts on a conveyor.
d) Parts that must not be touched such as freshly painted parts, sterilised parts or aggressive media or live parts such as electronic compo-nents, busbars and transformers.
e) Small and low-mass parts, e.g. components and all measurement objects where a contact probe draws too much heat, thereby causing incorrect measurements.

However, you must always ensure that the measuring spot of the measuring instrument is smaller than the measurement object!
...only conditionally suitable for:
Metal oxides, as these have an emission level that is mainly dependent on the temperature (between 0.3 and 0.9).
In this case, you should either apply a substance with a defined emission level (e.g. testo emission tape order-no. 0554 0051, lacquer or oil) or determine the emission level by means of a comparisonmeasurement with a contact thermometer.

...not suitable:
For bare metals to which no materials that increase emission level such as tape, lacquer or oils can be applied. Here, a high error rate can be expected due to the high level of reflection on the measurement object surface.
