FREEZEmarker B

The FREEZEmarker® B is a single-use indicator that provides an easy-to-read visual signal when there has been exposure to a freezing temperature for a short period of time, for example, during shipping.

When the indicator temperature remains at or above 0°C, the green circle with a white checkmark inside the circle is visible in the Active Zone (Fig. 1).

When exposed to temperatures at and below -2°C, the green circle with a white checkmark inside the circle will partially or completely change to white opaque/cloudy, showing that a temperature excursion has occurred, and the endpoint has been reached (Fig. 1). If uncertain whether endpoint has been reached, press the circle with your fingertips to evenly distribute the white particles.
