Racetech Irreversible Temperature Indicating Stickers let you document temperatures that can't be measured during actual use. Each strip has 8 or 9 calibrated windows that change color permanently as soon as a specific temperature is reached. Because the color won't change back, you can see the peak temperature after the part has cooled.
These miniature 0.71" W x 2" L (18mm W x 51mm L) labels can be used on hundreds of components, from oil tanks to shock absorbers. You can even find out how hot the inside of the trailer gets in the summer. Sold in packs of 10 strips of one temperature range. Our part numbers refer to the highest temperature in each range in degrees Fahrenheit (refer to the tables below).
