Thermax® Irreversible Temperature Labels provide clear, permanent visual evidence that specific temperature thresholds have been exceeded. Each indicator window irreversibly changes colour when its calibrated temperature is reached, creating a tamper-evident record of cumulative heat exposure.
These labels are widely used across manufacturing, logistics, storage and quality assurance applications where monitoring maximum temperature exposure is critical. Once activated, the colour change cannot be reversed, ensuring reliable verification during audits, inspections and receiving checks.
The Thermax® range includes single-level, multi-level, clock and precision formats, allowing users to monitor one or multiple temperature points depending on application requirements. Labels are compact, easy to apply, and require no power source or reader.
Typical applications include:
Manufacturing and process monitoring
Equipment overheating detection
Industrial storage and transport
Maintenance, servicing and warranty verification
Quality control and compliance documentation
Thermax® indicators are supplied ready to use and provide a simple, cost-effective solution for irreversible temperature monitoring.
