An adhesive, irreversible, visual alert device that clearly indicates if a product has been exposed to temperatures below a critical threshold.
Some chemicals, solvents and most importantly all vaccines can not be exposed to freezing temperatures, to do so could render them ineffective. Without an indicator or a data logger attached to these valuable products, it can be difficult to verify that a freeze event took place within the supply chain.
Available Trigger Thresholds
- ColdMark | -3°C
- ColdMark | 0°C
- ColdMark | 5°C
- ColdMark | 10°C
Operation | Simple installation with adhesive backing for fixing the temperature indicator to the package and clear visual indication of temperature excursion
Quality | Proven solution manufactured to the highest standard, overseen by ISO9001 procedures.
How it works | The ColdMark indicator bulb turns from clear to violet when the temperature goes below a predetermined threshold. In this example, the 0°C indicator is shown but it will vary according to the threshold temperature that you choose. Please refer to the ColdMark instructions in the “Downloads” section for more details.
