The LIMITmarker® I-C is a single-use indicator that provides an easy-to-read, irreversible visual signal when there has been exposure to a temperature above the threshold limit. LIMITmarker technology is based on the precise melting of heat-fusible materials at specified temperatures.
When the indicator temperature remains at or below 49°C, the small circle within the dark circle remains lightly colored (Fig. 1).
When temperatures at and above 51°C have been reached for over 15 seconds, the light area darkens (Fig. 1).
Response Time15 seconds
Shelf Life6 years from date of manufacture
Size8 mm with 3 mm active circle
Placed on product or product unit box. Pressure-sensitive adhesive, for flat surface applications.
For LIMITmarker, Response Time is time above the upper limit of tolerance. The upper limit of tolerance is the response temperature plus the accuracy, e.g. 50°C ±1°C has an upper limit of tolerance of 50 + 1, or 51°C.
