- Aquarium Thermometer Strips, Adhesive Kombucha Beer Brewing Temperature Strip, Stick On Strip Thermometer Sticker for Fish Tank/Fermentation Jar (39 to 97℉/4 to 36℃) Terrarium Water Temperature Test

Order these strips specifically for my wine cooler fridge. I just didn't trust the gauge on it. I used a kitchen meat thermometer to stabilize the cooler at 55°F. Used a scotch tape to attach strips to the bottom, middle,and top of a glass door.As you can see, the readings are pretty accurate. I'd say to 1°F. However, the lower the reading, the harder it is to see. If you can't seem to see what part of the scale is activated, shine a flash light on it at an angle.Don't forget to remove a clear protective film on the front side. It makes it a lot easier to read the temperature!

Works fine for sourdough starter

They stick really well to my kombucha jar.

These can be a bit difficult to read, but they work well for getting a quick idea of the temp. I use them with heating wraps for 2 gallon Kombucha jars. They've helped me ensure a consistent temp is maintained. I don't know if I'd rely on them for precise measurements.

Easy to use, accurate temp readings.

Seems to work, but the color of the current temperature is barely visible in most lights. YOu have to shine your phone light on it to see where the temp is.

they work great!

READ THIS BEFORE YOU PURCHASE-- This is 1 of the worst PET products sold on Amazon. They not only didnt work, but when I went to peel it off to send it back, it stuck to my tank + has ruined the glass. This company SHOULD PAY for my my time + my beautiful tank!!
