Temperature-Indicating Labels

Horizontal

Vertical

Continuously monitor surface-temperature changes. The temperature windows instantly turn from black to green when surface temperature reaches the temperature points. They return to black when the surface cools. Labels are self-adhesive.

Store in a cool, dry place below 64° F with less than 50% humidity.

One-Time-Use Single-Point Low-Temperature-Indicating Labels

Often used with cold-sensitive chemicals, paints, and electronics, these labels have a window that permanently turns red when your surface's temperature drops to the temperature point. Labels are self-adhesive.

Store in a cool, dry place below 64° F with less than 50% humidity.

One-Time-Use Single-Point Temperature-Indicating Labels

Temperature-Indicating Label with
Multiple-Exposure-Duration
Thresholds

See at a glance whether inventory has been exposed to high temperatures during shipping and storage. These labels are self-adhesive.

Labels with multiple exposure-duration thresholds have three windows that turn red permanently when your surface heats to the temperature point for brief, moderate, and prolonged periods of time. They won’t begin to monitor temperature changes until you pull their activation tab. Before activating, place them in an environment at least 9° F (5° C) below their temperature point for 30 minutes.

Temperature-Indicating Barcode Labels

Confirm your product wasn’t too hot or cold throughout shipping and storage. With just a scan from your barcode reader or smartphone, these labels inform you whether your packaging surpassed the temperature point. Once they're past the point for at least two hours, the barcode lines fill in to give you a unique code. The code changes again at four hours, so you know how long your product has been exposed. A compatible app shows you the results. You can also integrate them into your existing scanning system to log a record. Scan once upon your product's arrival or implement multiple scans along your supply chain to catch storage errors as they occur.

For accurate monitoring, keep them somewhere at least 6° F below their temperature point for two hours before use. They won’t begin monitoring temperature until you pull their tab.

Choose a temperature point that suits your application. 32° F labels are ideal for frozen products. Use 43° F labels for refrigerated products. 46° F labels are often used to monitor lab samples. 77° F labels are typically used for products best kept at room temperatures, such as adhesives.
