RAYTEK Infrared Temperature Sensor RAYCMLTJ
The CM is a potent, small, integrated infrared sensor that is intended for continuous temperature monitoring. If your application is sensitive to noise, it can simply replace standard contact probes with a user-scaleable 0-5V output or a J-type or K-type thermocouple output.
