Zebra Environmental Sensors - Ready to Use Indicators

Gain visibility into the temperature exposure of products — medications, vaccines and more — with a simple card or self-adhesive indicator. Our sensors support a variety of stability profiles, manufactured by Temptime®. Ready-to-use indicators reveal excursions of products exposed to excessive heat or freeze events, improve process efficiency, and protect margins due to products inadvertently exposed to damaging conditions.
Trust BarcodeFactory and Zebra Technologies to monitor high-value products with highly effective irreversible and reversible indicators.


Monitor Temperature-Sensitive Products

LIMITmarker® Threshold Heat Indicators

LIMITmarker irreversible visual temperature indicators can be applied directly to heat-sensitive products; available with delayed (2 hours), quick (15 minutes) or immediate (seconds) indication. Many medical products can be damaged and lose strength when exposed to temperatures above a certain threshold.

When exposed to temperatures at or above the response temperature, the heat indicators change color within a specified response time to give a visual warning.

LIMITmarker® Reversible 18°C Indicators

LIMITmarker Reversible 18°C indicators provide a visual cue when products that require refrigeration to maintain their efficacy reach room temperature. The indicator is solid blue when cold (at or below 8°C), then changes color and reveals "OK" when it approaches room temperature (18°C, plus or minus 2°).

The indicators are 16 mm x 10 mm self-adhesive labels, easily applied to the primary packaging of products, where they can be viewed and intuitively understood by users.

FREEZEmarker® Freeze Indicators

FREEZEmarker irreversible visual temperature indicators monitor exposure to freeze events. When exposed to a freeze event at or below the response temperature, the freeze indicators turn partially or completely white, obscuring the white checkmark, to warn that the temperature limit has been exceeded and the endpoint reached.

Many medical products can be damaged and lose strength if they are frozen. Such excursions can go unnoticed during shipping and storage.

TransTracker® Shipment Indicators

Monitor temperature-sensitive products across cold chain logistics from manufacturer to distributor, and hospital, clinic or pharmacy to the patient or end user. Provides accurate temperature monitoring with visual signals inside multiple unit packages or shipping boxes.

Helps you comply with increasing regulations, limit the waste of products incorrectly suspected of heat or freeze damage, lower the cost of reshipping medications or perishable food, and ensure user confidence and satisfaction.


Innovative Features

Provide Assurance to Your Customers

Gives customers critical information about their heat and freeze sensitive products.

Precise Indication That Matches Your Product's Profile

Accuracy is critical. Our precise ready to use indicators are available in several different response temperatures and response times to support the stability profiles of your products.

Save Costs Associated with Reships

Protect your margins from re-shipments of products where there is uncertainty about damaging temperature exposure during cold chain transport or storage.

Why use Zebra's Ready to Use Indicators?

Zebra's ready to use indicators give customers critical information about their heat and freeze sensitive products. They provide peace of mind and confidence that their products have not had a temperature excursion using an objective, easy to understand and clearly visible monitoring device.
