FREEZESAFE temperature drop indicator (pack 100 units)

The FREEZESAFE temperature drop indicator is an adhesive label that, by means of a color change, alerts us that the temperature has dropped below a critical value. The color change is permanent and irreversible, so it acts as a control indicator, recording the event. It is supplied in packs of 100 units.

The FREEZESAFE label is an adhesive sensor for monitoring temperature drops. Knowing whether the correct temperature has been maintained is essential for the cold chain. This self-adhesive label provides evidence of whether your product has been exposed to critically low temperatures.

The FreezeSafe temperature indicator accurately and irreversibly shows whether there has been an unwanted temperature drop below the optimal threshold.

Its operation is simple; just stick it on the product or box of products to be monitored, and the indicator will change color from transparent to magenta if the temperature drops below the established value for a sufficient amount of time. As soon as the temperature drops, the indicator changes from transparent to magenta until it reaches the shade shown on the label.

The indicator is irreversible, so once it has changed due to a drop below the critical temperature, it remains permanently magenta, alerting of what has happened. This allows you to check later if a product has been subjected to an unwanted temperature, during transport or storage.

FREEZESAFE is a simple and economical method to control the temperature drop during the cold chain as well as the transport of medicines, vaccines, food and other products, which if exposed to freezing temperatures, or simply cold, can be damaged.

The color change is gradual, allowing you to see if the exposure to the unwanted temperature has been momentary or continuous. The label has a sample point with the magenta hue that will reach the control point after being fully exposed. This allows us to compare the magenta dot to the sample to see if it has only been exposed for a short period of time, in which case the magenta shade will be lighter than the sample, or if it has been exposed for the full amount of time, in which case the color shade will be like the sample.

For each temperature, there is a specific time in which the dot will fully reach the magenta hue. The available temperatures and times required for the complete color change are detailed in the following table.

Uses of the Freezesafe temperature drop sensor

This temperature drop control label is an economical solution that allows you to monitor transport containers (box, pallet, etc.) or even stick the indicator directly on the product.

The Freezesafe can be used during the storage of products that require compliance with the cold chain. It will act as a safety device against the presence of an abnormally low temperature at any time during the product's lifespan, thus preventing an unwanted loss of its properties.

A visual check of the indicator alerts the recipient if the temperature has dropped critically, allowing them to quickly decide whether to accept or reject the product.

Main users of the sensor for thermal monitoring of the cold chain

  • Pharmaceutical manufacturers and distributors
  • Diagnostic laboratories
  • Transport companies
  • Logistics organizations in the food and beverage industry

All of them rely on this temperature indicator to:
