ColdMark descending temperature indicators are single-use devices that provide accurate, irreversible evidence of a below-temperature deviation.

The ColdMark turns from clear to violet when the temperature goes below a predetermined threshold.

ColdMark temperature indicators help determine if your you determine if your products have gone below an acceptable temperature. Without them, your product may be compromised from an unnoticed breach in your cold chain. These descending temperature indicators are single use devices that provide accurate, irreversible evidence of a below temperature deviation.

Temperatures can vary dramatically during transit. The cargo hold of an aircraft can be colder than you planned. Your product may encounter unexpected delays and be stored in less than ideal conditions. ColdMark temperature indicators provide a cost effective tool for monitoring the temperature of your package. ColdMark temperature indicators are single-use devices that provide accurate, irreversible evidence of a below threshold deviation. The ColdMark turns from clear to violet when the temperature goes below a predetermined threshold. With the information you gather from these indicators, you can make smarter decisions across your cold chain.

Why should I use a ColdMark Indicator?

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

Is the ColdMark resettable?

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

What should I do if the ColdMark indicator 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 the ColdMark be mounted?

The ColdMark should be located where it will be visible to the receiver of the monitored shipment.
The ColdMark 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 ColdMark temperature has been breached?

When the ColdMark is exposed to temperatures below the stated activation temperature ±1°C,
the indicator’s bulb will turn from clear to violet.
If upon receipt the ColdMark bulb appears milky white, the ColdMark has been subjected to temperatures
that caused the indicator itself to freeze. The indicator bulb will change to violet when it thaws.
A milky white or violet bulb are both indications of a below temperature threshold breach.

How should the ColdMark be stored?

ColdMark indicators should be stored at least 5°C above the indicator’s stated activation temperature
and up to 43°C.

How long does it take for the ColdMark to activate?

The indicator will respond in 30 minutes or less. Colder temperatures will speed the response time of the
