The stainless steel probe has a 1/2" NPT thread on the end. The probe is 200mm long, 8.5mm in diameter and comes with a 3 meter long cable. Just drill hole in your plastic fermenter, fit it with a standard airlock grommet and push the probe in for an airtight seal. No need for a thermowell this probe is made to last. With the sensor immersed in the wort you can measure the actual fermentation temperature. You can maintain better control over your fermentation temperature by controlling wort temperature instead of the of the air temp in your fridge which can easily vary 5 to 10 degrees. The probe is also suitable for hot applications up to boiling.
