Model IRtec includes options such as a choice of optics, temperature ranges and wavelengths. The miniature infrared temperature sensor has dimensions of 0.7 x 5" and accuracy of up to +/-0.05 percent of reading or 2°F (1.1°C). The unit includes a 4 to 20 mA signal output and measures temperatures up to 2,900°F (1,593°C). Other features include NIST-traceable calibration and working ambient temperatures up to 140°F (60°C) without requiring cooling.
