Thermowells are installed onto brewing pots and kettles to allow a thermometer probe or even a temperature controller sensor to be inserted through its hollow tube. It is also used to keep the temperature sensors away from the liquid that it [thermowell] is immersed in. It protects the device from being exposed to the elements such as the flow-induced forces, pressure, and chemical effects of the boiling wort. The process fluid then transfers the heat to its walls which is then picked up by the sensor.
While this weldless thermowell kit is compatible with ordinary brewing thermometers, it can also work well with other temperature control sensors.
