Infrared thermometers

  These hand-held infrared thermometers are extremely suitable for fast non-contact temperature
meas­ure­ments. Equipped with laser for easy aiming at the object. With adjustable emissivity for
different surfaces. Applications: for example in the food, automotive and chemical industries, in the
process technology and for research purposes.
