P250 C
Temperature Range: 450°C to 1400°C
Highly Accurate Two Color Portable Infrared Non-Contact Pyrometer
P250C is specially designed two color portable IR pyrometer for non contact temperature measurement between 450°C to 1400°C in demanding industrial environments with high accuracy. This is the two color pyrometer which 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.
