How to Mount Temperature indicators are best suited for monitoring product or the controlled environment of the product. WarmMark ascending temperature indicators are best used when mounted directly to the product being monitored or when placed inside the product shipper. Indicators should not be placed directly on gel packs, phase change materials, etc. as this will result in measuring the temperature of the packaging material components instead of the temperature of the product or environment. In rare cases, temperature indicators are mounted on external packaging to monitor ambient temperature conditions. www.spotsee.io 2
