Time Temperature Indicators
HEATmarker is a miniaturized, self-adhesive temperature monitoring indicator that can be applied directly to temperature-sensitive products. HEATmarker gradually changes color as heat exposure accumulates. When the gradual color change surpasses the reference color the user can identify if the product has exceeded its temperature limit.
Make Time-Temperature Monitoring Easy: HEATmarker features color-changing technology enabling the identification of potentially degraded products so action can be confidently taken. The indication area, initially light in color, becomes darker when exposed to heat. When the cumulative heat exposure has reached the limits of its profile, the indicator will either be the same color as or darker than the outer ring surrounding it.
Preserve Product Supplies: HEATmarker provides a visual cue to allow users to preserve product supplies and maximize inventory efficiencies by using products that haven’t reached their endpoints, and disposing of only those products with HEATmarkers that have reached their endpoints.
Sophisticated Chemistry Supports a Variety of Product Stabilities: Featuring patented technology, HEATmarkers are available in options to support the stability of your product. For example, a HEATmarker Hx indicator (37°C specification temperature) with 9 days to endpoint would be used for a less stable product while a HEATmarker Hx indicator with 36 days to endpoint would be used for a more stable product.
Models: HEATmarker Hx Series, HEATmarker Hu Series, HEATmarker M, H and E
