WarmMark QR is a simple, single-use temperature sensor that does not need a battery. You can scan it with a smartphone to check if a product was exposed to temperatures that were too high. The scan records the time, date, location, and sensor number, then sends the information to the SpotSee Cloud.

The indicator changes from white to pink or red when the temperature limit is exceeded. This gives everyone in the cold chain a clear and easy way to check the condition of temperature-sensitive products during shipping.

ColdChain Complete is a simple and affordable way to monitor temperature-sensitive products. Its single-use indicators clearly show when a product has been exposed to temperatures that are too hot or too cold. Once activated, the result cannot be reversed.

FreezeSafe QR is a simple temperature indicator that shows when a product has been exposed to temperatures that are too cold. The color change is permanent, so the result cannot be reset or hidden.

Scan it with a smartphone to record the product condition, time, location, and sensor number. The information is then sent to the SpotSee Cloud.

It does not need batteries, special readers, or an app. FreezeSafe QR helps companies find temperature problems, improve handling, and reduce product loss during shipping.

SpotCheck shows the current temperature of an object with a simple color change. As the temperature rises, the large circle changes from blue to green, then to brown-red.

The color change is reversible. When the temperature drops, the indicator changes back through the same colors..
