10Pcs Thermochromic Temperature Change Stickers - Lab & Industrial Surface Temperature Indicators(10 Grids 50~100℃ Reversible)

There is a row of squares on the small sticker, representing different temperature values. When the temperature rises to this temperature point, the squares will turn black, and even if the temperature subsequently decreases, it will not revert to the color, so that we can know the higher temperature that the object has experienced, and we can know whether there is overheating without long time of monitoring, or use the test paper as a evidence of qualified
