SL sensor label from Telatemp Corp. records warming temperatures. The highly visible label can be used to monitor temperature-sensitive materials such as plastics, machinery, pharmaceuticals, electronics, adhesives, biologicals and food during shipment, storage, processing or operation. The chemical sensor in the middle of the label provides a permanent color change from silver to black when exposed to the rated temperature. It is available in temperature values of 105, 110, 115 and 120°F (41, 43, 46 and 49°C) as well as every 10°F (~6°C) increment from 120 to 350°F (49 to 177°C).
