This useful thermometer allows you to quickly see whether vegetables, cheese, meat, and other items are being stored at the correct cooling temperatures, thanks to the printed cooling zones. This way, prematurely spoiled food will soon be a thing of the past. With the practical hanging hook, you can easily hang it in your refrigerator or freezer. The product is entirely made in Germany. The capillaries are filled with a specially colored thermometer liquid, and mercury has not been used for a long time.
