Horizontal Stick On Thermometer Strip, Digital Temperature Display for Fermenting, Brewing, Wine, Beer, Kombucha or Aquariums. 50-90F (10-32C) Adhesive Sticker 5 or 10 Pack (5)

So my son received a Sea Monkey kit for Christmas. These are supposed to be the world's 2nd easiest pet I believe....well I'm not sure about that. The instructions say the water, which you put inside a very tiny plastic tank, is supposed to be in the 80+ degree range for these lil suckers to hatch. I'm not sure how you're supposed to know the temp since you're warned not to put a thermometer inside the tank. After several days of no hatching, lots of panicked momma research, lots of obsessing by my Autistic son....these stick on thermometers were on the way!! They helped immensely and worked within seconds to let us know we needed to warm up the water a tad! My son could easily follow the color grid and find our where the temp was at, which he loved!! Thanks for a great product!!!

These thermometer strips are an affordable and convenient way to monitor temperatures for fermentation. I use them for kombucha brewing, and they stick well to my glass jars. The readings are clear and easy to read, and they work just as expected.The only drawback is that the temperature increments are grouped together, so you don’t get super precise readings. That said, for the price, they’re a great solution for general temperature monitoring. If you need an exact temperature down to the degree, you might want a digital option, but for quick reference, these work great!

Works great

I have 3 of these on 3 tanks. I have a digital thermometer gun and they read between 1 and 2 degrees off which is fine by me.

Easy to use, seems pretty accurate. I use iton my kombucha brewing jar and keep temp around 82 degrees.

Recently, I decided to get into baking sourdough bread and found out that it would be good to have this type of thermometer on the jar with the sourdough starter, since the temperatures are very important for having success with sourdough.The thermometer is very easy to apply via the sticky backside. However, it appears that they tend not to stick perfectly to the glass. On one side the end did not lay down. No biggie, I use rubber bands to mark the volume of the starter, so I just put another one over the thermometer. Time will tell if they hold up being handled often and also when they get wiped down.It is undoubtedly VERY helpful to be able to see the temperature right there on the vessel you use for your project.

These are easy to read and work great for monitoring brewing vessel temperatures at a glance. I saw several bad reviews from people who thought these were for reading body temperature, they won't, they don't read that high. You should also take care not to use hot water when cleaning your brewing vessels. the hot water could damage the temp strip and render it unusable. Use warm water and a brewing sanitizer to clean your brewing vessels.

Much too large of temp brackets to really know the correct temp.,also it is off with temps too. returned it . There's much better stick on one's out there
