Part Code: A250C



A250C PL/TL is a highly accurate digital two colour IR pyrometer from A series family for non contact temperature measurement. The Pyrometer 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 two colour IR Pyrometer is used to measure the temperature in variety of applications in Forging, Annealing, Welding, Sintering Rolling mills, Cement, Glass, Crystal growing and many application where low temperature to be measured in ratio technique.
