The standard Unisense thermosensor, TP2000, is a mineral insulated thermocoupler with a tip diameter of 2 mm. The thermosensor can be used for most applications where a temperature measurement is required for monitoring or temperature compensation purposes.
The Unisense glass thermo microsensor consists of a thermocoupler inside a tapered glass capillary. This sensor can be used to determine temperature micro gradients in different environments e.g. hot springs biofilms, compost piles, and sediments with steep temperature gradients due to volcanic activity.
