Six millimeter round labels are unmarked and ideal for monitoring electronics for warranty related overheat instances.

Specify your preferred temperatures when requesting a quote.


This special unmarked security Temp-Plate® temperature sensitive label has four heat sensitive indicator "positions" that turn permanently black when the rated temperature is reached.  The customer can select any four available temperature points from 100°F (37°C) and 350°F (176°C).  This micro four position label is one of our smallest, and is round.

Useful for warranty work and specialized applications. No temperatures are printed on this label.  A legend supplied with each box provides the identification of each point. Easy, self-adhesive installation on most surfaces. Careful selection of the temperature points allows for detection and recording of most overheat occurrences.  Each temperature position is clearly printed with the rated temperature.   Labels are sold in a recloseable box of 10 labels.

0.25 inch (6mm) diameter.

NIST Calibration data is available for this label.

Built in Asheville, NC USA.

Note that all Temp-Plate® labels containing a temperature position of lower than 110°F/43°C are considered low temperature and must be shipped with an ice pack via overnight service to prevent the labels from turning in transit.
