A450C FO-PL is a highly accurate digital two colour radiation Fibre Optic IR Pyrometer from FO-PL series. This device measures the temperature of an object by calculating the ratio of the energies at two different wavelength bands.
The ratio technique eliminates and reduces errors in temperature measurement caused by changes in Emissivity, Surface finish and energy-absorbing materials such as water vapour etc.
The Fibre Optic Pyrometers are widely used in high ambient temperature applications without cooling up to 250°C and also in processes involving electromagnetic interferences.
