If you are looking to measure the temperature of your fermentation directly from the wort, simply install this extension probe into your RAPT Fermentation Chamber. The RAPT is designed to heat and cool your entire fermenter. This is the ideal scenario as the whole fermentation vessel is placed in a temperature-controlled environment which gives you the most even temperature and most precise control of your fermenter. This 2m (6.5') Extension Probe allows you to easily measure and control the temperature from right inside your fermenter, allowing for super precise readings throughout the fermentation.

This is a simple plug-and-play fitting for your RAPT. For the highest accuracy, run through a 2-point calibration in the settings menu.

The probe diameter is 4 mm (0.15").
