ColdMark Freeze Temperature Indicator Stickers

One-off indication of temperature breach (range -3°C to +10°C) with Temperature Indicator Stickers

The ColdMark descending temperature indicator stickers are a user-friendly and intuitive solution for the cold chain marketplace.

These devices indicate exposure to temperatures below a predetermined threshold by producing a clear indication.

The single-use temperature indicator stickers are specifically designed to help shippers identify and correct gaps in their biomedical, pharmaceutical, and food product cold chains. The result is increased knowledge of your product’s environment when it is out of your sight and out of your control. That translates into improved product margins by protecting product shelf life, ensuring validated packaging is performing correctly, and reducing packaging costs.

When you use the ColdMark ShockWatch temperature indicators, you can monitor the temperature of every shipment. You and your customers know whether your consumable products have been exposed to unacceptable temperatures – and whether the duration of exposure was long enough to compromise safety and desired characteristics during shipment or storage. You can also use the devices to monitor incoming shipments of raw materials, so you know whether your ingredients and raw materials are safe to use.

Use ShockWatch products to reliably monitor temperature and duration of temperature deviations so you can better determine the safety and quality of your goods as they move through the supply chain.
