Selection Guide

Reference Guide to the most widely used materials and thermocouples for ultra-high temperatures (types B, C, R & S).

Heavy Duty with Standard Plug

Heavy duty, ultra-high temperature thermocouples (types B, C, R & S).

Heavy Duty with Conduit Head

Ultra-high temperatures to over 4,200°F with conduit head attached available in various sheath materials for vacuum furnaces.

Heavy Duty with Flex Leads

Thermocouple for vacuum furnaces and ultra-high temperatures. Special heavy duty design for Graphite furnaces (types B, C, R & S).

Heavy Duty, Tungsten Coated

Special thermocouple for Ultra-high temperatures in Graphite furnaces. Tungsten coated sheath dramatically extends lifetime.
