Thermax

Thermax Irreversible Temperature Indicators provide a fast, reliable, and cost-effective way to monitor heat exposure across a wide range of industrial applications. These self-adhesive labels change color permanently from clear to black when a specific temperature threshold is exceeded, creating an accurate and irreversible record of thermal events.

Designed for surface-level monitoring, Thermax indicators are widely used for process validation, equipment monitoring, and preventative maintenance. They are especially valuable in industries where heat exposure must be carefully controlled, including drying, bonding, curing, and transport operations.

Compact and easy to apply, Thermax indicators offer businesses a simple yet powerful solution for verifying product integrity and compliance with heat-sensitive processes. For manufacturers and logistics providers in South Africa, Thermax labels ensure reliable temperature history tracking, reduce risk of undetected damage, and support strict quality assurance protocols.

  • Irreversible indication: Permanent color change (clear to black) once threshold is reached

  • Wide temperature range: Available from 29°C to 290°C (84°F – 554°F)

  • Accurate performance: ±1°C up to 99°C; ±1.5°C to 154°C; ±1% above 160°C

  • Easy to apply: Self-adhesive backing adheres to most surfaces

  • Water, oil & steam resistant: Withstands harsh environments

  • No activation required: Ready-to-use on arrival

  • Traceable: Can be attached to inspection reports for documentation

  • Temperature Range: 29°C to 290°C (84°F – 554°F)

  • Accuracy:

    • ±1°C / ±2°F (29–99°C)

    • ±1.5°C / ±3°F (100–154°C)

    • ±1% +1°C / ±1% ±2°F (160–290°C)

  • Color Change: Clear to Black

  • Type: Irreversible

  • Mounting: Self-Adhesive

  • Format: °C and °F

  • Overheating detection for motors, gears, and components

  • Process verification in sterilization, curing, bonding

  • Quality assurance in cleanroom or cold chain logistics

  • Validation of temperature during machinery maintenance

  • Proof of compliance with regulatory thermal thresholds

  • Select the appropriate temperature indicator for your target range.

  • Peel and stick the label onto a clean, dry surface.

  • Monitor the indicator; when the rated temperature is exceeded, the relevant panel changes from clear to black.

  • Remove and attach to inspection report for validation (if required).
