Overview

WDJ series temperature indicator label is a kind of thermometer-type temperature monitoring sticker and it has the unique color-changing temperature indication function. These self-adhesivelabels consist of a series of temperature-sensitive elements sealed between heat-resistant substrates with transparent windows, that can permanently record the highest temperature exceeded and it’s irreversible.

These temperature indicator labels used to monitor the temperature of the contact points of the equipment and the surface of the object, and can be used in electricity, railways, and medical treatment, pharmaceuticals and other industries.

Once the monitored temperature reaches or exceeds a certain temperature point on the sticker, the point on the sticker immediately changes from white to black. When the temperature rises to a higher temperature monitoring point, the monitoring point also changes from white to black, change color in turn, just like a thermometer.
