A250C
Temperature Range: 350°C to 1350°C
Highly Accurate Two Color Online Infrared Non-Contact Pyrometer with Bluetooth V2.0
A250C PL/TL is a highly accurate digital two colour IR pyrometer from A series family for non contact temperature measurement. The Pyrometer measuresthe 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.
