The Temperature Indicator display a permanent, non-reversible color change that clearly shows the highest temperature reached. Simply attach the Indicator label to the product or dosimeter to be monitored - it's that easy.
The temperature range is 27.5°C to 65.0°C (81.5°F to 149.0°F)
The Indicator provides a highly accurate (±1.0°C) temperature measurement, and provides incremental temperature points from 27.5°C to 65.0°C (in 2.5°C increments). A permanant supertack adhesive keeps the Indicator flat against the surface, providing the necessary thermal contact needed for the chemicals in the label to react and register the precise temperature reading.
