11.1 Emissivity values for Cyclops 100L and Cyclops 160L models
In order to obtain accurate temperature measurements, the emissivity value
of the target surface must be known. This section of the User Guide contains
typical emissivity values of the most commonly measured materials for each
thermometer variant.
Where no emissivity value is quoted, this means that the thermometer may be
unsuitable for the measurement application, the temperature of the target is
outside the thermometer’s measurement span, or that the emissivity value cannot
be accurately specified and should be determined in-situ (See Section 11.2). If
you have a query regarding the emissivity of the target in your measurement
application, contact AMETEK Land for assistance.
