Temperature indicator

Hi,

I am looking possible alternatives to labels e.g.

Change-of-State Temperature Measurement Devices
Change-of-state temperature sensors consist of labels, pellets, crayons, lacquers or liquid crystals whose appearance changes once a certain temperature is reached. They are used, for instance, with steam traps - when a trap exceeds a certain temperature, a white dot on a sensor label attached to the trap will turn black.

which are indicating temperature. I am looking for the cheapest way of measuring and also need some visualization that confirms temperature. This label cost around 0,5 €.

Are there any cheaper products for measuring temperature?

Thx.

It depends what temperature range you want to measure and how accurately. For example, a blob of wax which melts above a certain temperature is about as simple and cheap as it gets.
