What if you need to know how long your product has spent above a defined temperature? What if your product can tolerate a number of exposures to an elevated temperature provided they are short lived?
Timestrip® PLUS indicators provide simple, quick and cost effective answers. They record elapsed time at or above a specified threshold temperature; for example at 8°C/46°F for up to 8 hours.
Timestrip® PLUS are small and self-adhesive so they can be attached directly to a product, package or shipment. They can be stored inert at room temperature and then activated without pre-conditioning when required.
Features & Benefits:
- Timestrip Plus™ ships deactivated to avoid accidental triggering during transit
- Instant activation notice when blister is depressed to let you know the product is working
- Sharp front line for very distinct and exact progression with no vague bleed through
- Unique hour markings provide exact run out times- no need for charts
- Activation temperature accuracy of ±1°C
- No pre-conditioning required
- No special storage or shipping requirements
- Long shelf life of approximately 2 years
- Splash resistant
- Fast melt point
How it works
All Timestrip® PLUS indicators work from three principles. A mixture will melt from solid to liquid form when an ascending temperature threshold is breached and return to solid form if the temperature falls again to its freeze point (STOP temperature). When in liquid form, the mixture will move laterally through a porous membrane at a known rate. The progress of the liquid will be visible through a viewing window.
Once any Timestrip® PLUS is activated, if the temperature being monitored remains below the STOP temperature, the blue colour will not move. If the threshold is breached, the blue colour will progress to the viewing window with the time markers. Each movement is irreversible so the cumulative time of any temperature breaches is shown by how far the blue colour has moved along the time markers.
Timestrip Plus Product Options
Timestrip Plus™ is available in 9 standard configurations for a variety of temperature applications, featuring combinations of these product parameters:
|Threshold temperature (or trigger temperature)|
|Stop temperature (temp where bleed pauses)|
|Run-out window (total time recordable)|
|8 Hrs||12 Hrs||18 Hrs||24 Hrs|
|Time marks in hours|
|1/2||1||2||4||8, 12||18, 24|
Additional temperature may be available on request. Actual size of indicator: 40mm x 19mm
