Review on Jansamn Brewing Thermometer Strip - Precise Adhesive Thermometer for Aquariums, Fish Tanks, and Kombucha - Temperature Range 39℉ to 97℉ & 4℃ to 36℃ by Joyce Brown

Several boxes from our food delivery service arrived with melted ice packs and I didn't want to guess if the food was at a safe temperature or if I had to throw it out. This heats up to 39 degrees (according to the company, food-safe temperatures do not exceed 41 degrees). So this one works! Our last delivery of food arrived melted and the box broke from meltwater, our food was 56 degrees (usually took 72 hours to deliver, it was supposed to be 24 hours). Although the food was a bit cold. knew exactly if it was 40 or 50 degrees, they came to the rescue and saved us from the food sickness! We threw food, what a waste. So they are accurate, they stay at room temperature, which is what our thermostat does and the internal thermometer reads. We place them (don't attach them to your packages, just use the way they're installed and read the temperature) directly on the outside of food containers (especially trays that are closer to the top or bottom). bottom of the box). Be sure to check how low the thermometer you buy is. If you're considering this one or a cheaper one, this was the only one I found, which was pretty cheap and a little more expensive than the others, but was more useful to me for a few things! This one goes up to 39, some only go up to 60 and doesn't help if you need it for safe food delivery. It can even come in handy when you get a grocery delivery and the goods are taking longer to check to make sure they aren't constantly sitting in the driver's trunk and getting hot. And don't throw them away, just keep using them until they no longer stick together to maintain a reliable temperature.
