Refractory Thermocouple Assemblies
Refractory fiber and cement laminate tubes have a maximum
service temperature of 1500°F (815°C). The tubes come
complete with a 20 gauge Type K thermocouple and 36” of
lead wire installed. This eliminates the need to buy them
separately. The tips of the tubes are made from silicon
carbide to increase the response time. Refractory tubes are
used in molten Zinc and Aluminum die casting applications.
These refractory tubes will not shatter like ceramic tubes.
They also will not contaminate the molten metal as a stain-

Refractory Floats are ideal for hand lading applications. They
will read the temperature 3” below the molten metal surface.
A silicon carbide tip gives them a fast response time. Ask one
of our sales engineers for details.
