Type T Thermocouple
Copper Constantan thermocouple material for low-temperature and moisture-prone measurement
Type T is a base-metal thermocouple type that uses Copper as the positive leg and Constantan as the negative leg. It is often selected for low-temperature, cryogenic, laboratory, refrigeration, and moisture-prone applications where stability at lower temperatures matters.
Thermometrics manufactures Type T thermocouple assemblies as wire sensors, probes, plug-and-lead sensors, surface sensors, and custom replacement assemblies built to drawing.
Common Type T RFQ details
Type T temperature range
Type T is commonly referenced for approximately -454°F to 700°F (-270°C to 370°C). The practical assembly rating depends on insulation, environment, conductor size, probe construction, and documentation requirements.
Type T thermocouple material
Type T uses Copper for the positive conductor and Constantan for the negative conductor. It is known for good low-temperature stability and is often reviewed when moisture resistance or cryogenic performance is part of the requirement.

When to review alternatives
Type E may be reviewed where higher EMF output is useful. Type K or Type N may be better for higher-temperature service. RTDs may also be reviewed where higher accuracy and repeatability are more important than thermocouple simplicity.
