LaserLiner CondenseSpot Manual De Instrucciones página 13

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 measure. 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.
