The Thrumometer is an in-line thermometer, ideal for measuring the temperature of your wort outflow from a counterflow chiller. The interior of this thermometer is mirror smooth, providing no places for bacteria to hide. This thermometer responds very quickly (1°F per second), has 1°F precision, and 0.5°F accuracy. It never needs calibrating. If you use a highly-efficient counterflow wort chiller, the Thrumometer will help you avoid over-chilling your wort, and will save water. This instrument is made from a head-treated highly corrosion-resistant aluminum alloy that will last a lifetime!

Requires 3/8" ID tubing. Should not be used with liquids exceeding 140°F.

Works well, but... Review by Ian
First of all, it works fine and each of my gripes are clearly printed in the description. I'd urge you to consider them before you make your purchase though, as they might not set-in until you go to use the device if your processes are similar to mine.

The unit shouldnt' be used above 140F. No big deal right, you're using it with cooled wort.. Well, I guess that depends - I like to sanitize my final loop from the kettle, through the plate chilller, then the hose to the carboy by pumping boiling wort through it for a while towards the end of the boil and back into itself. I can't do that with this attached, and subsequently negate some of my efforts when I have to add it after the fact.

It's also silly that it's not 1/2". My blichman plate chiller fitting set is all 1/2 barb, so you end up having to step-down or buy another barb for this guy. I might try to stretch some hot silicone tubing over the 1/2" in the future to see if that doesn't make it useable.

Anyway, it is a great little item - just a couple of irritants that have rendered it a paperweight as my setup has gotten more advanced. (Posted on 8/9/14)
Excellent Review by Chris
Easy to read and clean, you couldn't ask for more.... except for it to be 1/2" instead of 3/8 hence 4 stars. (Posted on 7/17/13)
Good Review by Steven
Works great ! A little spendy , but it is blichmann. It does the job. Looking forward to dialing it in and using it many batches! (Posted on 7/15/13)
Perfect Review by GAGE
Works great for me, have it at the end of my counterflow chiller going into the carboy, gives me accurate readings!! (Posted on 10/27/12)
Lagers? Review by Mark
This works fantastically well, yet not when I am trying to knock out lagers at 50F. It would have been a much better instrument if the range was 78F-48F. I've ended up rigging a ss dial thermometer with a 1/2"mpt ss T after my therminator instead. (Posted on 2/26/12)
Great product Review by SRB
Works as advertised. Simple to use and simple to clean. (Posted on 7/20/11)
Great way to dial in your chiller flow. Review by Matthew
I like this because I can adjust my valve settings to get the wort flow through my chiller as fast as possible, chilling down to pitching tempratures.

I also clean and sanitize while still plumbed to my pump and Therminator. (Posted on 11/10/10)
Much easier this way! Review by DarkNoonBrewer
I simply plumb this in stream after the chiller, and it makes keeping track of the wort temp much easier than holding a thermometer in the stream. I sterilize with it connected to the hose and never had a problem with the sticker. Maybe i havent left it in long enough to hurt it yet...

Works great! (Posted on 7/19/10)
For over two years, has worked great Review by Nathaniel
I attach it in-line with my boil pot out spigot hose, to get an accurate final reading of wort temperature as it hits the primary fermenter, and it works great.

One small note -- the thermometer is really just an aquarium-type liquid crystal strip attached with high strength clear tape. Not shabby or low-quality by any means, but one day I left it sitting in some B-Brite too long, and it did bubble the tape up. Still seems to work fine, but if your going to clean it by dunking it in sanitizer like I do, defiantly don't keep it there longer than a minute or two.
