Stick On Thermometer Strip for Fish Tank, Aquarium Thermometer, Kombucha, Beer & Wine Fermentation - Vertical Temperature Strips w/Color-Changing Display, 50–90°F (10–32°C) (10-Pack)

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 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.

These do what they say they do. Works pretty good for what we need it for

I use these for my kombucha Jar.

Fast delivery. Accurate temp. Easy to use and read

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

I use these on my water kefir jar to monitor the temp. I reuse the jar for a couple of weeks and have no problem with it staying on the jar. I can move it to a new jar once, maybe twice before it loses its sticky. I occasionally check the temp using my thermoworks and the strip is accurate enough for my needs, is within a couple of degrees of the thermoworks.

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.

excelente, el justo lo que buscaba!

Can’t beat it for the price and it’s an easy way to tell the temp of a bucket while making wine and cider!

stick very well

Ya llevo puestas dos y no marcan ????? bastante que desear yo no las recomiendo, las devolveré Pésimo no lo compren

These are so small they fit better on a cup than on a carboy
