5.5 Mounting

To mount the pyrometer, a threaded drilling M12 is located on the underside of the unit. The pyrometer can be
attached to different mountings.
We recommend to use the retaining bolt supplied with the pyrometer or the optional available ball and socket
mounting support with clamp or thread. This mounting plate ensures secure assembly of the pyrometer (for
order data see Accessories (section 3.3) at page 5).
5.6 Emissivity
The emissivity is the relationship between infrared energy radiated from an object and the radiation energy of
a perfect emitter (black emitter) at the same temperature and the same spectral range.
The emissivity is material-dependent and of a considerable size in order to be able to determine the temper-
ature of an object accurately without contact. The emissivity of the object being measured must therefore be
known and be adjusted at the pyrometer.
Typical emissivities for various materials are available on our homepage at www.kleiberinfrared.com or in rele-
vant literature.
The instrument is calibrated at black body radiation ( = 1,00). Real objects have an emissivity less than
1.00. This difference can be adjusted with changing the emissivity value from the pyrometer.
