Omron ES1B 140-260C Temperature Sensor IR Temperature Sensor, 3m Cable, -25°C to +70°C

The Omron infrared thermosensor it has an electromotive output as high as that of a thermocouple, thus connecting directly to the thermocouple input terminal of the temperature controller is possible.

Unlike thermocouples the thermosensor does not deteriorate
It maintains stable and real-time temperature control
