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

I taped these to the sides of my glass and plastic fermentation jars and they do a great job of tracking temperature in my cool basement. The temps can vary from 75F in summer to 60F in winter so knowing will help determine which yeast types to use. I have a few yeasts (Red Star Premier Rouge) that will stop below 64F. Lalvin D47 does best below 68F. Now I can pair the best yeast with the environmental temps.

These stick-on thermometers are great for hobby-style wine making. I place one of these on the each carboy (6 gallon) and I am able to see if I am straying the recommended range for the yeast to thrive. Seems to work well, No drama here!!

They work great! Easy to apply. Hopefully waterproof/resistent.

So far these have been very useful, they keep good readings, and stick firmly to the jar. i use them form kombucha making, and they've been great.

These stick-on thermometer strips are easy to read in bright or slightly dim light and adhere really well. So we'll, in fact, that once you stick them on, you can't take them off again without destroying the thermometer strip. Not a big deal since you get a bunch of them in the package but it's just that you have this positioned exactly before pressing in place. These work by changing colors on the strip, corresponding to the temperature. Reading the temperature is not an exact science as you need to make a guess if there are two adjacent numbers that have a color change. I like these because the numbers are big enough to see easily and they are inexpensive enough that I can stick them on everything that I want to monitor the temperature of. I use these on the outside of my beer fermentation vessels, both conical and bucket fermenters as they don't need a super precise reading. I don't think I'd use these on something super hot, like a bbq grill or smoker since they would probably melt.

Fast delivery. Accurate temp. Easy to use and read

Works as advertised

The colors on the thermometer are not as bright as shown. I tried to get a picture, but unfortunately my cellphone camera corrects for the inadequacy. You have to lean in and look closely to see the colors. I wanted obvious and I can distinguish colors quite easily. I was also looking for a smaller strip they take up more viewing space on the front of my aquariums than I would like. Anticipate roughly a 2x 6 inch strip. They will suit the overall purpose that I bought them​ for which is a secondary warning system if the aquarium temperature is going above​ an acceptable level. Aquarium heaters fail more often than they used to and I can walk by and notice much faster than I would with a glass thermometer plus they are cheaper than a digital ones that stop working after several months.
