OMEGALABEL™ is a self-adhesive temperature monitor consisting of a heat-sensitive indicator sealed under a transparent heat-resistant window. The indicator circle turns from light gray to black at the temperature rating shown on the card. Color change is not reversible and provides a temperature history of the surface being monitored. To serve as a permanent record, the OMEGALABEL™ can be removed and attached to an inspection report.
OMEGALABEL™ accuracy is guaranteed to be within +/- 2% of temperature rating. The Series 21 OMEGALABEL™ is conveniently mounted on sheets (21 per sheet) for fast, on-the-spot application by just peeling them off one at a time. The adhesive backing easily adheres to any clean, dry surface.

1. What is the shelf life for the non-reversible temperature indicating label? 2. Will repeated temperature below the prescribed temperature cause the label to turn black? Thanks James

Asked by: JamesN
Hi, 1. It depends on the temperature of the label. 2. If is at a below temperature for a long period of time it will cause the label to turn black, some labels need to be stored in room temperature. Please feel free to reach out to to better understand your application and assist with purchasing the correct product for your needs. However, we hope this helps.
