LIMITmarker I is a high-heat threshold indicator that monitors temperature and immediately indicates when the heat exposure is at or above the response temperature.

If the colour of the centre indicator circle matches or is darker than the outer circle, the endpoint has been reached, indicating that the predetermined threshold heat profile has been exceeded.

When LIMITmarker I indicators are exposed to temperatures at or above the response temperature, the center circle will match or will be darker than the outer circle, the ENDPOINT has been reached within the specified response time.

LIMITmarker is placed on products or the product unit box and pressure-sensitive adhesives are available for flat surface applications.
