SS Brewtech Weldless Thermowell - 8"
A thermowell is a tubular fitting used to protect temperature sensors like the thermometer or thermocouple. The tube is closed at one end and open on the other, and is made from a solid bar stock that has been drilled to create the straight bore. It is mounted to the process stream by means of sanitary caps, threads and a welding process. Its weldless design can easily be retrofitted into a brew bucket for convenience.
It can also be installed by drilling a 17mm hole on the kettle. This particular thermowell is 9 inches in total length, and extends 8" into the vessel. It has a tube opening of 6.5mm so it cannot accommodate thick thermometers. It is most compatible with a small heat sensor such as the Ss Brewtech LCD temp display for digital readings of temperature.
So your question might be, how does this provide accurate temperature readings? The boiling wort transfers heat efficiently to the thermowell wall which is then picked up by the thermometer or sensor. By placing the thermometer into the tube it is protected from the heat of the wort directly. The thermowell is a tool that can help not only protect your thermometer or heat sensor, it also allows home brewers to take accurate readings.
