LIMITmarker I-P

The LIMITmarker® I-P 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 43°C, the small circle within the dark circle remains lightly colored (Fig. 1).

When temperatures at and above 45°C have been reached for over 15 seconds, the light area darkens (Fig. 1).
