Thermax® 5-Level Clock Temperature Labels (Pack of 10)
SpotseeDescription
Pack Size: 10 Indicators
Thermax® 5-Level Clock Temperature Labels provide fast, accurate and permanent indication that a surface has exceeded specific temperature thresholds. Each of the five circular cells darkens irreversibly once its rated temperature has been reached, giving a reliable visual record ideal for process monitoring, quality checks, and equipment diagnostics.
Key Features
- Five irreversible temperature cells per clock
- Permanent colour change – cannot be reset or tampered with
- Circular design ideal for compact or curved surfaces
- Self-adhesive backing for quick application
- Suitable for a wide range of industrial and laboratory uses
- Supplied in packs of 10 indicators
How They Work
Each temperature point contains a calibrated heat-sensitive element that melts and migrates at its activation temperature. When exceeded, the cell permanently darkens, leaving a clear visual record that the threshold has been reached. This makes Thermax Clock indicators ideal for audit trails, maintenance, validation testing, and process verification.
