It is found in other laboratory environments as well.
The type t is a very stable thermocouple and is often used in extremely low temperature applications such as cryogenics or ultra low freezers.
A thermocouple is an electrical device consisting of two dissimilar electrical conductors forming an electrical junction a thermocouple produces a temperature dependent voltage as a result of the thermoelectric effect and this voltage can be interpreted to measure temperature thermocouples are a widely used type of temperature sensor.
