Adhesive thermometers

Temperature indicator labels are adhesive stickers with boxes changing their colour when the temperature indicated on the side of each box is achieved.   You just have to attach them to the surface to control and these stickers will record the temperature reached. There are two types of these adhesive thermometers:
  • Irreversible thermometers: The colour change will not be reversed. The temperature sticker works as maximum or minimum temperature recorder and informs if certain temperature has been reached or not
  • Reversible thermometers: These paper thermometers work conventionally, as they indicate the temperature of the product or surface at that time and turn back to their original colour when the previous temperature is reached again.

Types of Adhesive thermometers

  • Irreversible thermometers

    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.

    Benefits of use of reversible thermometers

    Self-adhesive liquid crystal strip thermometers have been gaining ground as they have been used as conventional thermometers because lots of their features turn them into more practical temperature measurement methods. 

    • Easy to use
      • Remove the protective paper
      • Stick on the surface to control
    • Easy to understand
      • The real temperature is displayed in deep green colour on black
    • Reliable
      • Accuracy of +/-1ºC and in strips for medical use +/-0.5ºC
    • It does not use batteries and does not contain toxic components 
      • No installation or spare parts required (unalterable  for more than 2 years)
    • Flexible
      • They can be used to measure the temperature of curved surfaces
    • Standard and customized versions available
    • Their production can be customized (temperature limit: -3ºC / +90ºC)

    Their temperature range is included between -3ºC and +100ºC and their accuracy is +/- 1ºC. Thanks to their versatility and accuracy, the use of reversible thermometers is very common even in the medical sector to monitor the patient's temperature during  surgical interventions

    Uses of reversible LCD products

    This technology has many applications:  it can be used with promotional items to reveal a message or a reward at the reach of a certain temperature or to be part of a work safety device. This one is based on the presence of a striking colour informing on the reach of hostile temperature inside a channel or piping in view and on temperature control inside refrigerated display counters or transparent door refrigerators in department stores and supermarkets.  In this way, customers may see and buy silos of perishable products that are stored in an appropriate thermal environment. Some of them are listed below:

    • Advertisements
      • Calendars
      • Promotions with hidden messages
      • Colour change cards
    • Nutrition
      • Food storage
      • Transport of refrigerated food
    • Medical / pharmaceutical industry
      • Conservation of vaccines
      • Refrigerated transport of vaccines and medicines
      • Incubators
      • Laboratories
    • Job security
      • Alerts of high temperatures inside piping or surfaces

Adhesive thermometers are very easy to use. The thermometer has to be stuck by the adhesive to the surface or the product to control.  In contact with the surface or the product, the temperature displayed by the temperature sticker exactly corresponds to that of the item being examined.  This temperature may be different from the one indicated by the oven thermostat, the chamber or the area where we are controlling the temperature.

Temperature recordings by temperature stickers

On the basis of the temperature control chosen, we can select the most suitable type of temperature indicator.

Unassisted control

If unassisted control is chosen, we will use irreversible temperature stickers as they will allow to post-control if the desired temperature change has been reached. This is particularly useful to control the quality production (sterilization, cooking, heat treatment of metals, ...) or to ensure that no overheating has occurred (boilers, motors, transportation of chilled goods...).

Continuous control

In the need of a label indicating the temperature of a product or surface anytime, reversible paper thermometers must be used. These indicators always show the temperature recorded instantly. Being reversible, they change as heat contained in the controlled product or surface increases or decreases.
