Frequently Asked Questions

How does the Freeze Watch indicator work?

The indicator contains a sensitive liquid in a specialized vial. When exposed to temperatures at or below the temperature threshold (-4°C or 0°C), the liquid undergoes a permanent color change to indicate that freezing exposure has occurred.

Can the indicator be reused?

No. Once the color change occurs, the indicator shows the complete temperature exposure history and should not be reused. Each application requires a new indicator label.

What surfaces are suitable for application?

The pressure-sensitive adhesive allows application to any flat, dry, and clean surface. Ensure the surface is free of dust, moisture, and oils for optimal adhesion.

What is the shelf life of unused indicators?

Unopened Freeze Watch indicators maintain full functionality for 5 years when stored at 5°C to 32°C (41°F to 90°F) with 20-60% relative humidity.

How should indicators be stored before use?

Store in original packaging at controlled temperature conditions of 5°C to 32°C (41°F to 90°F) with 20-60% relative humidity. Protect from direct sunlight and extreme conditions.
