3M Freeze Watch
3M™ Freeze Watch™ indicators are ideal for products that are at risk of quality degradation when exposed to freezing temperatures during transportation or storage. This applies to products such as food, paints, adhesives, chemicals, pharmaceuticals, diagnostics, etc
.The patented design of the 3M™ Freeze Watch™ indicators consists of a highly sensitive indicator liquid in a special ampoule. Freezing the liquid leads to the destruction of the ampoule. When it thaws, the indicator paper behind the ampoule becomes irreversibly discolored. This signals that the product quality needs to be checked
.3M™ Freeze Watch™ indicators are available with temperature limits of -4 °C and 0 °C in order to be used for different product sensitivities.
3M™ Freeze Watch™ indicators are attached in or directly to the transport containers. They reliably monitor the transportation and storage of temperature-sensitive products.
