Pack Size: 10 Micro Strips
SpotSee® Thermax Micro Irreversible Temperature Labels provide compact, high-precision monitoring wherever space is limited and accurate heat exposure records are critical. Each strip contains four temperature cells; when a cell’s rated temperature is exceeded, it permanently changes colour to give clear, tamper-proof evidence that the threshold has been reached.
The Micro format is designed for applications where standard Thermax strips are physically too large or where you need discreet indicators on small components, assemblies or instruments. Typical uses include electronics, medical devices, small enclosures, bearings, motors, printed circuit boards, laboratory equipment and validation work.
Once any cell has activated, the colour change is irreversible. This provides a permanent record of the highest temperature reached, supporting quality assurance, traceability, warranty investigation and audit/compliance requirements.
Key Features
- Ultra-compact “Micro” format for tight or crowded installations
- Four irreversible temperature cells per strip
- Permanent colour change for secure, tamper-proof indication
- Quick response to temperature excursions
- Simple to read and easy to interpret on site
- Pressure-sensitive adhesive backing for fast application
- Supplied in packs of 10 strips
How They Work
Each cell on the Micro strip contains a specially formulated, heat-sensitive element. When the surface temperature reaches or exceeds the cell’s rated value, the element melts and migrates, changing from a light to a dark state. This reaction is irreversible – once a cell has turned, it cannot reset – providing a permanent visual record that the temperature point has been exceeded at some time during use, transport or storage.
Typical Applications
- Monitoring heat-sensitive electronic components and assemblies
- Validating process temperatures on small instruments and tools
- Ensuring maintenance or service work does not overheat assemblies
- Monitoring motors, gearboxes, bearings and drive systems
- R&D testing and product development where space is limited
- Quality control and warranty / service investigation
