Ceramic Coated Cast Iron Thermocouple Tubes

For measuring the temperature in molten aluminium up to 800 degrees Celsius.

The ceramic coating gives an additional 300% longer service life than uncoated protection tubes. These tubes are typically used in melting furnace where mechanical impact is an important issue.
