Industrial Thermocouples
Thermometrics designs and manufactures precision thermocouples for demanding industrial and scientific environments. Our sensors are built with high-grade alloys, reliable junctions, and customizable sheath configurations for accurate temperature measurement in harsh applications.
General Purpose Thermocouples
Versatile sensors for general industrial use.
Types of Thermocouples
Type B
Suitable for extremely high temperatures (up to 1700 °C); used in glass and steel industries.
Type E
High sensitivity for low-to-moderate temperatures; ideal in cryogenics and oxidizing environments.
Type J
General-purpose thermocouple; reliable in vacuum and inert environments (−40 °C to +750 °C).
Type K
Most common type; broad range, rugged, and cost-effective up to 1260 °C.
Type N
Stable and oxidation-resistant; great for aerospace, reactors, and lab testing.
Type R
Platinum-based for high-temperature applications (up to 1600 °C); highly accurate.
Type S
Similar to R, but with superior long-term stability; used in pharmaceuticals and refining.
Type T
Highly accurate at low temperatures; ideal for cryogenic and food-grade monitoring.
