WarmMark

A Smart, Connected Solution for Cold Chain Monitoring

WarmMark, a time-temperature indicator sticker, provides insights into your cold chain logistics so you will know which packages may have experienced thermal damage and which were handled properly.

This single-use temperature recorder for shipping turns red when it reaches the temperature threshold you selected. Then, unlike many temperature indicator stickers, WarmMark starts a countdown, with its three individual indicator dots changing color for brief, moderate, and prolonged exposure. Those durations vary by temperature. So, for example, “brief” exposure means 2 hours at 0°C/32°F, but means 30 minutes at 25°C/77°F and above. Based on the temperature and exposure, you’ll know whether a product remains safe and effective or whether it should be replaced.
