Here’s a really easy project that helped me with a simple problem. Since I’m using a picnic cooler for a mash tun, I don’t have a reliable way to measure my mash temp. I am uncertain exactly what water temp I need to set my HLT for to get the desired mash temp using a HERMS setup. The inline mash temp will go between the mash outlet of the HLT as it returns to the top of the mash. I can then set my HLT temp based on the output temp of the HERMS coil.
I am also finally going to break down and buy a plate chiller. Since I am using quick disconnects on this thermometer, I can also use it to measure the temp of the wort as it exits the chiller. I can then adjust my water flow accordingly.
There are 4 parts in my configuration; a 1/2″ mpt thermometer, a 1/2″ stainless T, a 1/2″ mpt x male camlock fitting, and a 1/2″ mpt x female camlock fitting.
Install took less than 5 minutes, just had to thread all the parts into the T.
Here is a shot of it mounted on the ghetto HLT.
Total cost for this project was around $39. You could change the input and output connections if you are not using camlock fittings. It would be very easy with a triclamp setup as well. Just get a triclamp T, 1/2″ female mpt x 1 1/2″ triclamp adapter, and a thermometer, then clamp it all together.
Here is a video of it in action. It worked perfectly!
