IT-3H2 is one item of IT-3 .IT-3 Infrared Temperature Sensor provides the advantage of infrared temperature measurement in a compact, integrated sensor. It measures target temperatures ranging from 300 °C to 2500 °C with three models. The unit's on board electronics are protected by an aluminium housing, allowing the sensor to function in ambient temperatures to 60 °C without cooling.
The sensor features coaxial laser sighting. The optical resolution is 150:1 and the smallest spot size is 2mm. Laser sighting and high-resolution provides the solution for either small targets or long-distance measurements. Standard features include adjustable emissivity which are 0.95, 0.9,0.85 and 0.8. It is suitable for ferrous metal with bad surface finish and some non-metallic material,Glass production .
