Production processes have always required monitoring to make sure that thermal processes or the preservation of certain temperature conditions have been complied correctly.  In recent times, the implementation of quality systems (ISO, UNE, ...) has implied a greater need of quality controls and exhaustive registers in industrial processes.

In this respect, irreversible thermometers have demonstrated to be a good solution as they are simple and low cost.

Operation of irreversible thermometers

Irreversible thermometers are based on a thermally sensitive melting wax. This technology is based on a series of temperature sensitive elements sealed between heat-resistant layers containing transparent windows which make colour changes visible.

Each irreversible temperature indicator changes colour when its calibration temperature exceeds. Its changes are irreversible and they show a temperature recording of the surface under control. Once peeled off, the labels do not deteriorate and they can be annexed to an inspection report acting as a proof of the temperature reached. 

Why using temperature irreversible strips instead of other kinds of sensors?

Manufacturers need to have a precise, easy to implement and low cost device just like irreversible temperature indicators. Moreover, they offer several advantages:

• they do not require batteries
• Immediate response
• Permanent recording of the maximum temperature
• Resistant to oil, steam and waterproof (and accuracy up to 3 atm)
• Wide temperature ranges available: +29ºC to +290ºC
• Clear colour change: white/orange to black
• Temperature control in inaccessible areas to operators
• Direct reading on the surface to control
• Cheap and easy to use solution

For this reason, irreversible temperature labels have a more extensive use in all applications.
