Thermax

Thermax 5-Level Temperature Clock Indicators are simple temperature monitoring packaging solutions with five-alarm stickers that change from silver to black individually as temperature rises above specific values. Each alarm sticker is triggered at a different temperature level to provide better data on the temperature during shipping. This colour change is non-reversible, preventing tampering and giving shippers and handlers visual evidence of temperature breaches.

The temperature-sensitive elements are indicators which use the sharply defined melting points of a series of specially purified organic chemicals to give unique, high-precision colour change effects. Each temperature point uses a different chemical compound and is made separately by applying a coating containing the chemical to a unique paper substrate. When the temperature is exceeded, the chemical melts and is absorbed by the substrate, causing a permanent colour change.

Thermax can be attached to almost any surface with its strong adhesive backing. This makes the packaging labels ideal for temperature monitoring as users can apply the indicator to the surface and monitor it later to determine the highest temperature. This is very useful when gaining a live reading is impossible, such as an automotive engine, gearbox and rollers or bearings, in a car, industrial machinery or aircraft.

There are a variety of different temperature points covered by a range of temperature strips. A good practice is to select a strip where the critical temperature is at the midpoint of the strip range. This will allow users to notice an approaching temperature to the crucial point and data on how much the critical temperature point has been exceeded.
