TemPro 550
5. Safety requirements
Inaccurate readings will result from measuring shiny or polished metal surfaces (stainless steel, aluminium, etc.). To
compensate, cover the measuring surface with masking tape or flat black paint. Allow time for the tape to reach the
same temperature as the material under it. Measure the temperature of the tape or painted surface.
The unit cannot measure through transparent surfaces such as glass. It will measure the surface temperature of the
glass instead.
Steam, dust, smoke, etc., can prevent accurate measurement by obstructing the unit's optics.
Make sure that the target is larger than the unit's spot size. The smaller the target, the closer you should be to it. When
accuracy is critical, make sure the target is at least twice as large as the spot size.
