Monitor Temperature-Sensitive Products

Choose from heat, freeze, reversible and shipment monitoring indicators based on your product's handling requirements and temperature stability profile.

Zebra LIMITmarker threshold heat temperature indicator
Heat Exposure

LIMITmarker® Threshold Heat Indicators

Identify potentially damaging exposure to elevated temperatures with an irreversible visual color change. These indicators can be applied directly to heat-sensitive products and packaging.

Different versions provide delayed, quick or immediate indication to help match your product's temperature stability requirements.

Response options: Approximately 2 hours, 15 minutes or seconds, depending on the selected indicator.

Zebra LIMITmarker reversible 18 degree Celsius temperature indicator
Reversible Temperature Indication

LIMITmarker® Reversible 18°C Indicators

Provide an intuitive visual cue as refrigerated products approach room temperature. The indicator is solid blue when cold and changes appearance to reveal an "OK" message near its specified response temperature.

The compact self-adhesive format is suitable for placement on primary product packaging.

Key specifications: Blue at or below 8°C; "OK" appears around 18°C (±2°C). Label size: 16 mm × 10 mm.

Zebra FREEZEmarker irreversible freeze exposure indicator
Freeze Detection

FREEZEmarker® Freeze Indicators

Help identify freeze exposure that might otherwise go unnoticed during shipping or storage. FREEZEmarker indicators provide an irreversible visual response when exposed to a freeze event at or below the specified response temperature.

The indicator changes to partially or completely white, obscuring its checkmark to signal that the freeze threshold has been reached.

Ideal for: Freeze-sensitive products requiring a visible indication of potential temperature excursions.

Zebra TransTracker temperature monitoring shipment indicators
Cold Chain Shipping

TransTracker® Shipment Indicators

Monitor temperature-sensitive shipments across the cold chain, from manufacturers and distributors to healthcare facilities, pharmacies and end users.

Visual indicators placed within packages or shipping containers help personnel assess temperature exposure and make more informed product-handling decisions.

Customization: Branding and application-specific consumer information may be available for TransTracker indicators.

Why It Matters

Greater Visibility. More Confident Decisions.

Ready-to-use visual indicators provide an accessible way to monitor temperature exposure without complex equipment or specialized reading devices.

Build Customer Confidence

Provide clear visual information about possible heat or freeze exposure to support more confident handling decisions.

Match Product Requirements

Select from available response temperatures and times to support the stability profiles of different temperature-sensitive products.

Reduce Unnecessary Costs

Improve visibility into potential excursions to help reduce uncertainty, avoid unnecessary product waste and limit avoidable reshipments.

Find the Right Fit

How to Choose a Temperature Indicator

The right solution depends on the product, the temperature conditions you need to monitor and how the indicator will be used.

Identify the temperature risk

Determine whether excessive heat, freezing or approaching room temperature is the primary concern.

Match the response profile

Consider the required response temperature, exposure duration and whether reversible or irreversible indication is appropriate.

Select the application format

Choose a card or self-adhesive indicator suited to the product packaging, shipping container or distribution process.
