8-temp Thermolabel contains 8 temperatures on a single label and is used to pinpoint an operating temperature. The labels are not compley sealed and thus cannot be used under liquids without protection. There are 10 combinations of overlapping temperatures, as shown on Table 1.
The illustration shows a TL8-130 label which has been heated to 150ºF. The top three sections have turned black while the remaining sections did not change. This ls that the temperature was between 150º and 160ºF
