Your temperature control will become even more precise if you take the following tips into account:
How do Testo's thermometer strips work?
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!
Temperature control with colour codes
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.
Documenting measurements: our temperature stickers can cope with this too
You can also deal with temperature control with virtually no effort using our measuring strips. Because you can remove the used measuring strips with the temperature information from the surface of the measurement object again without any problem. As the adhesive surface is reusable, you then simply attach the measuring strips to your inspection report or the temperature documentation.
Measuring strips from Testo – keep going as long as you want
Measuring strips that have been attached properly (without any bubbles) adhere firmly and reliably to the measurement object. They do not come off even when confronted with substances such as oil, petrol, solvents or water. They can only be taken off manually. For instance, if you remove the measuring strips by hand in order to stick them into your documentation.
