Thermometer strips determine the surface temperature of the measurement object within temperature zones or as a maximum value. For temperature control, the self-adhesive films are simply stuck onto the measurement object.
If the temperature limit values are exceeded, the measuring strips have a lightning-quick reaction with irreversible color changes. This enables reliable detection of whether limit values have been exceeded.
Testo’s temperature stickers are frequently used in many industries for temperature control. For example, it can be commonly found in the electrical industry, automotive engineering, research and aerospace technology.
Because their efficiency is unbeatable when tasks such as preventive maintenance, quality assurance, or proof of warranty abuse are involved. You will find out about important background elements and application tips for professional temperature control with measuring strips here.
Thermometer strips are ideal for efficient temperature control. They are easy to use and provide very reliable results. Your temperature control will become even more precise if you take the following tips into account.
Although there are sophisticated chemical processes behind the way measuring strips work, they are in principle very simply designed. Temperature-sensitive elements are located under a transparent protective layer. These are the so-called phase-transforming indicators. The temperature measuring strips themselves consist of different mixtures of chemicals, which are produced on special absorptive paper substrates.
If the pre-defined temperatures are reached, the chemical melts and is absorbed by the substrate. The chemical reaction is shown by the change of colour. Important: the colour that develops is irreversible because the chemical reaction can only occur once. Further temperature fluctuations no longer have any influence on the colour. Perfect temperature control guaranteed!
There are heat-sensitive elements in the thermometer strips, mini indicators and measuring points. Chemical reactions are triggered at defined temperatures and these are shown as a change of colour: the original silver or gold-coloured temperature surface changes to grey through to black.
