Temperature indicators, in the form of self-adhesive measuring strips or measuring points, are a sensible and economical alternative to thermometers wherever continuous long-term monitoring of temperatures is required. They are often more suitable for small or moving parts, which may be subjected to vibrations. If the maximum temperature is exceeded, an irreversible colour change takes place in these heat-sensitive measuring devices. Their quick reaction time enables an instant reaction, which can help prevent damage and reduce costs. Our range includes temperature indicators, which continue to function even in contact with oil, water or steam. Our range also includes special temperature-sensitive chalks, which change colour to display temperature changes on surfaces.
