Why should I use a FreezeSafe Temperature Indicator?

The FreezeSafe Temperature Indicator alerts you if the item being monitored has been exposed to a temperature below the specified threshold of the device.

Is FreezeSafe resettable?

No, FreezeSafe is not resettable. It is a one-off use indicator and is always armed for monitoring.

What should I do if FreezeSafe is activated?

If the indicator has been activated in transit, you should contact the shipment sender to determine the appropriate course of action.

Where should FreezeSafe be mounted?

The FreezeSafe can be adhered directly to the product being monitored or located inside the packaging. Test in house where the appropriate position is for your particular shipments

How do I know the FreezeSafe temperature has been breached?

When the FreezeSafe is exposed to temperatures below the stated activation temperature ±1°C, the indicator will turn from clear to magenta.

How should the FreezeSafe be stored?

FreezeSafe should be stored out of direct light between 15°C and 25°C

How long does it take for the FreezeSafe to activate?

FreezeSafe will respond in 30 minutes or less for the 0°C version and 90 minutes for the 2°C version . Colder temperatures will speed the response time of the FreezeSafe.
