Product Description

For the measurement of higher temperatures, we offer thermocouples with ceramic tubes, upon request with additional ceramic inner tubes. The thermocouples (e.g. type S or type B) are insulated by a 2-hole or 4-hole insulating ceramic rod. The measuring point is laser-welded. The thermocouple is protected against environmental influences.

We furnish all kinds of thermocouples with ceramic protective tubes at all lengths and designs.

* High accuracy       
* Good stability  
* Wide temperature range: 0-1800 degree
* Long serving time
