Note: If you select Accredited Calibration Certificate (IPAC) when purchasing this product, click the Product Customization TAB and fill in the second field (TEXT - Required temperature calibration points.) with the respective required points or simply attach a copy of a calibration certificate.

To optimize surface temperature accuracy with infrared thermometers:

Determine the emissivity of the object to adjust the spectrum range of the instrument that can be used for measurement.
Avoid reflection from other sources of temperature by thermally enveloping the object to be measured
For high temperature objects, use smaller wavelength instruments when possible.
For semi-transparent materials such as plastic films and glass, make sure that the bottom surface (behind the object) is uniform and below the temperature of the object.
Hold the instrument perpendicular to the surface of the object when the emissivity is below 0.9.
In all cases, do not exceed the 30 degree angle of incidence.
