Tests to 160 Degrees Fahrenheit The temperature measurement is visible by the thermocromatic color-change band on the label. When the wash cycle reaches 160 degrees Fahrenheit, the band changes colors from blue to orange. The label measures temperatures within +/- 2 degrees Fahrenheit. Ideal for Record-Keeping After use, the label is easily removed and added to the facility\'s records. Because it features 2 blanks, one for a signature and another for a date, the label makes logging the temperature of your machine fast, easy, and accurate. With the label on record, you can efficiently monitor the performance of your dish machine and ensure that all dishes are properly washed prior to use. Easy to Apply The label features an adhesive backing to easily stick to a dry item, such as a glass or plate, prior to the item being loaded into the dish machine. From there the label, which is waterproof, is run through the machine and measures the temperature during the wash cycle. It is for a single use only.
