Temperature-changing patch

The temperature-sensitive patch indicates the surface temperature of an object by undergoing color or state changes at specific temperatures, utilizing temperature-sensitive materials. Its function is to monitor curing, drying, or storage temperatures in industries such as coatings and plastics. Applications include detecting baking temperatures and verifying temperature records during cold chain transportation.
Selection
When selecting a variable temperature patch, ensure it matches the target temperature range and consider the patch's response time and accuracy. Confirm the substrate adhesion and observe the clarity of color changes. Pay attention to the influence of environmental humidity and check temperature calibration certifications. Choose the type based on whether the requirement is for single-use or reversible applications.
