Product Details

Specifications

1.thermocouple
2.type: S-type ,B-type ,R-type
3.testing temperature in industrial production
6.good interchangeability

Model:High temperature furnace thermocouple for electric furnace

1. top quality high temperature thermocouple

2. Platinum-rhodium thermocouple, also known as high temperature precious metal
thermocouple, is divided in 3 types: S-type thermocouple (Pt Rh 10- Platinum
thermocouple), R-type thermocouple (Pt Rh 13- Platinum thermocouple), B type
thermocouple (Pt Rh 30- Platinum and rhodium 6 thermocouple),

3.as well divided into single and double Platinum-rhodium.

4..They are suitable for high temperature situations, widely used to test the temperature| in glass,
ceramics and industrial production processes such as salt bath furnace.
