Temperature Sensitive Paper, Temperature Indicating Sticker, 10Pcs/Set Surface Temperature Indicator, Thermochromic Label Sticker, Lab Research & Industry (5 Grids 219°F-260°F)

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 return to the original 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 quality

• To remove the temperature measuring paper, a little skill is required. First bend the bottom paper and then remove it, If you are not skilled in uncovering, please use a knife to shovel along the bottom paper from the side. Do not pick at random to avoid damage
• The temperature measuring part pasted shall be flat, clean and dry without bubbles, and the oxide layer and concave and convex surfaces shall be removed by sandpaper polishing, or cleaned and wiped once with gasoline and other solvents. The temperature measuring paper is attached with pressure sensitive adhesive, which shall be pressed firmly with hand pressure during pasting to ensure that the tiny air gap between the bonding surfaces is eliminated, so that the bonding effect of the bonding surface is exerted under pressure, so as to make the bonding firm. Please pay attention to cleaning the surface when pasting on the parts that may be stained with oil and water
• Wrap a large piece of transparent tape in a place with particularly harsh environment, which can play a better role in protection and fixation. If necessary, it can also be pasted with electricity. First, stick the patch to the small insulating rod at the tip, push the adhesive side to the equipment, and then it can be easily stuck on the equipment. Note that it is forbidden to touch with hands during temperature measurement to prevent damage to the product
• The measuring range of each type of temperature measuring test paper is different. There are two display modes of Celsius and Fahrenheit on the test paper. Please select the appropriate style according to your use needs
