The Blichmann ThruMometer In-line Thermometer is a great way to know the temperature of your wort while it's being transferred. Very helpful when using a counterflow or plate chiller to read the temperature of your wort going into the fermenter. Made of heat-treated highly corrosion resistant aluminum. Reads from 58°F - 88°F, and has 3/8" in and out posts.

Note- Clean with mild detergent only, using warm (no hotter than 140°F) water. Do not soak in the same bucket as other metals, as this could result in galvanic corrosion to the aluminum. After use, dry thoroughly and store in the protective plastic tube.

Works Great
Just used for the first time yesterday. Pretty responsive temperature readings allowed me to adjust on the fly.

Favorite purchase to date
I use this with my Grainfather and SS Brewtech Brew Bucket. I attach it to the counter flow chiller tube on one end and another piece of silicone tubing on the other. I feed the out tube through the hole in the fermenter lid so the fermenter remains covered entire time. I use the thermometer on the brew bucket as well to monitor the blended temp of the wort. This allows me to monitor the overall blended temp as the temp coming out of the chiller changes or if I make adjustments (water flow rate and/or temp) with the chiller. I find that the temp readings change swiftly and are reasonably accurate. For my set up, this is my favorite purchase to date and highly recommend anyone using a counter flow chiller to buy this. Takes a lot of stress out of chilling because you know what temp the wort is as it comes out of the chiller.

Does what its supposed to do
Excellent product, has made life a lot easier for regulating flow from the chiller in order to hit the right temperature.

I used a piece of 3/8" tubing on the input port, and it fits into the 1/2 " tubing coming from the chiller with no leaks.

A must have if using a therminator. Blichmann makes everything easy.

Works Great
I wish there was an option for 1/2" input/outputs instead of just 3/8" but overall the product works very well. I was worried it would take too long to wait for the colors to show up accurately on the gauge but my experience has been temps show correctly after only a few seconds of contact with the flowing wort.

Great Item
I use this on the output of my heat exchanger and it works perfectly. Easy to clean, and the response time of the therm strip isn't too bad either.
