This is a 4mm replacment probe that you can use to replace the 6mm Probe that normally comes with the MKII temp controller that we sell here:

The main reason for this is that that this smaller probe fits into the 4mm thermowell that is on the side of our reflux and pot stills.

By using the MKII Temp controller box it will enable you to automate the distillation process so you dont have to wait around watching the still for so long.
