Education: How do they work




Our smallest temperature sensitive label. Available in 9 options covering a range of 40°C to 224°C (104°F to 435°F). These labels are the smallest irreversible temperature indicating labels we carry, and they cover a wide range of temperatures. Perfect for recording maximum temperatures in locations where space is limited, or where the use of traditional thermometers or electronic temperature measuring devices is impractical.

Adhesive backed temperature sensitive label that reacts to increasing temperature with a permanent colour change. Versatile, accurate and 100% reliable.

TI 4 Level Micro Indicator Labels are available over a range of 40°C to 224°C (104°F to 435°F).

If an indicator has been exposed to a temperature in excess of it's rating, it provides a tamper proof display of temperature achievement.

Widely used in the pharmaceutical, electronics, aerospace, automotive and food production industries

  • monitoring transportation and distribution
  • providing evidence of a thermal disinfection temperature achievement
  • confirming soldering temperatures
  • monitoring engine component temperatures for warranty claims
  • confirming temperature integrity in machine maintenance
  • warning users that environmental conditions exceed temperature limits

If placing the indicators in an environment where they can be exposed to oil or aggressive conditions we recommend the labels are sealed in place on a clean dry surface with one or more layers of clear epoxy.

When using these indicators, ensure they are kept only in refrigeration temperatures and NOT deep freeze situations. The labels must be applied to a dry, clean surface to ensure proper adhesion.

Please also note that touching the indicator may activate the indicator in summer months, especially if ambient temperature is at or around 29?C.
