This versatile strip utilises materials with thermochromic properties to change colour depending on the temperature of the surface that it is attached to. As such this can then be used as a quick visual reference for a vessel containing a heated liquid, over time the temperature will change and the colour will change accordingly. Great for coffee cups!
The strip has an adhesive backing and a protective film. It measures 450mm x 20mm and can be cut to length to fit most sizes of canisters.
These strips can also be used to determine the approximate difference in temperature between two areas. As such, they can be used to indicate the level of the liquid in butane gas canisters or foam/liquid level in a fire extinguisher. The product here is demonstrating thermal conduction and the principle of a heat sink.
