2°C / 36°F Low Temperature Excursion Indicator
Timestrip® Descending TD404 is a single-use, irreversible low-temperature indicator designed to provide immediate visual evidence when a temperature-sensitive product is exposed below 2°C / 36°F.
TD404 is designed for refrigerated shipments and other applications where a product must remain above a critical minimum temperature, even though that minimum is still above freezing.
The indicator is self-activating and continuously monitors temperature. If temperature drops below 2°C / 36°F, the indicator permanently changes from green to red, providing a clear visual indication of the breach.
Ideal for pharmaceuticals, vaccines, biologics, medical products, refrigerated foods, life-science materials, chemicals, and other cold-sensitive products.
Too Cold? Know Immediately.

Know When Your Shipment Gets Too Cold
Detect Exposure Below 2°C / 36°F
Not every cold-chain product can safely approach freezing.
Some refrigerated products must remain above 2°C / 36°F throughout transportation and storage.
TD404 continuously monitors for temperatures falling below that minimum threshold and provides an irreversible visual indication if a qualifying low-temperature excursion occurs.
Green = No Breach
Red = Temperature Dropped Below 2°C / 36°F
Self-Activating Temperature Monitoring
No Manual Activation Required
TD404 requires no manual activation.
The indicator is self-activating and continuously monitors for low-temperature breaches, making it simple to deploy across refrigerated shipments and high-volume cold-chain programs.
