Platinum rhodium thermocouple Comments:
1. Produce based on client's requirments
2. Methods of fixing: normally without fixing device, but flange or threaded is available

Temperature sensor B type Platinum rhodium thermocouple with 0.5mm thermocouple wire is actually a double platinum-iridium thermocouple with index B. It can measure the temperature of the medium from 0 to 1800 °C and can be used for a long time at 1300~1600 °C. It is the best thermocouple for high temperature measurement.
