Having accurate temperature reading is very important when mashing grain to make beer and during fermentation. This video describes how to install an ETC temperature probe so that it provides the most accurate readings and gets the quickest response time possible.

Hi, and welcome to another BREWHA video. In this video I want to show you how to best install the ETC temperature probe so that you get the most accurate temp reading and the quickest response in the control possible.

The ETC is going to arrive with a cord grip loosely on the temperature probe and you are going to have a thermowell (on your vessel). The thermowell in this video is going into the reducing Tee portion of the Condensing Assembly but you’ll also have the thermowell that is in the bottom of the 3-in-1 or if you have the Mash Tun or the Hot Liquor Kettle you are going to be putting a theromwell in there as well.

Once you have installed the thermowell, you want to take the heat transfer compound (most vessel packages include two syringes of silicone based heat transfer compound) and put it right to the very bottom of the thermowell and squeeze it in. If you are purchasing heat transfer compound just use a q-tip or bamboo skewer or something else to make sure that the heat transfer compound gets right in to the very tip of the thermowell. The heat transfer compound, as the name implies, is very helpful because it takes the heat on the outside do the thermowell (in the vessel) and conducts it right into the temperature probe so that you can get the quickest and most accurate reading possible.

Then take the cord grip that is on the ETC temperature probe and loosen it off so that it is not pinching the wire. You should be able to slide the cord grip up and down on the temperature probe wire, just like that, and slide the temperature probe into the hole of the thermowell. Don’t tighten it up yet, you want to be able to spin on the base without tightening the cord grip and you screw the base all the way in to the thermowell until just the base is just in and tighten it until it is snug. Then the cord of the ETC probe should be able to slide in and out, push it so that it is all the way and you can feel it hitting the end of the thermowell and then tighten the cord grip. The cord grip is going to grab onto the ETC cord and ensure that it doesn’t come loose. If it pulls out, it will not be reading inside the vessel, or in this case, in the condensing assembly, and it is going to be reading some other temperature (external) and you are going to super heat or the temperature is going to rise too high because the ETC will not be measure the temperature accurately. So push it all the way in, tighten it until it is firm.

And there you have it. That is going to make sure that the ETC is giving you the most accurate temperature reading and the quickest response time possible.
