Setting the emission coef cient
10
1.
A built-in sensor head detects the material/surface-speci c infrared rays emitted by every object. The level of
these emissions is determined by the material's emission coef cient (0.01 to 0.99). This instrument is preset
to an emission coef cient of 0.95, which is applicable to most organic materials as well as plastics, ceramics,
wood, rubber and stone. For details of those materials with a different emission coef cient, please refer to
the table.
Unknown emission coef cient:
Apply masking tape or black matt paint to the surface of the area whose temperature you wish to measu-
re. Wait until the tape/paint has heated up. The temperature of the surface can then be measured with an
emission coef cient of 0.95.
