As they are irreversible, they allow for temperature controls easily and in a non-assisted manner. They only need to be stuck on the area or product you want to control.   

Afterwards, they will indicate if the temperature has been reached or not, because, although it decreases, if the temperature was reached at any time, the change of colour remains.  

These labels are available from 29ºC to 290ºC. Supplied in packets with 50 units.

IMPORTANT NOTE: In models with lower temperatures (29ºC – 34ºC) a special treatment is needed. See the technical information.

Supply: Packets with 50 units of the same temperature.

Dimensions: 12 x 13 mm

Type: Square

These temperature indicators are resistant to water and oil. They are made of heat-sensitive material that reacts to temperature, changing the colour to black when reaching the thermal level at which they are regulated. This material is coated with transparent polyester to isolate it from liquids or other substances.

The back side is made with adhesive so that they can be stuck on any surface. They are flexible; therefore, they can be placed on curved surfaces.

Accuracy is <+/-1ºC> for temperatures up to 100ºC and <+/-1%> for temperatures above 100ºC.

Temperatures lower than the body heat

For thermometers with ranges of temperature lower than the body heat (29ºC – 34ºC), some precautions need to be taken. Delivery is carried out with cold accumulator and must be stored in the fridge when received. Gloves or tweezers are required when handling the indicators in order to avoid them from being activated by the body heat.

All indicators are made in accordance with ISO 9001 standard.  

With regard to regulations on chemical substances and their presence in the product, the temperature labels meet REACH Annex XVII 

Uses of the 1-level irreversible thermometer

The 1-point temperature label can be applied to any sector. This irreversible-type indicator is ideal for any control which needs to monitor a process, ensuring that a specific temperature has been reached or not. The permanent colour change will be used to ensure the result.

As it is a 1-temperature point indicator, it is particularly suitable when only monitoring a thermal value, as it will be the lowest-cost solution. In addition, its size allows it to be placed on any surface, no matter how small it is. For temperature controls when a range of various values need to be monitored, the other indicators of the product range will be needed.   

Its application is not limited to a specific sector as it is a general-purpose type. From controlling food cooking to manufacturing photovoltaic modules or disinfecting surgical equipment. It offers numerous solutions. Some of them are detailed below:

  • Industry
    • Aluminium lacquering
    • Thermal treatment for mechanical parts
    • Manufacturing of photovoltaic modules
    • Temperature control in autoclaves
    • Manufacturing of cans for food
  • Food
    • Sterilisation of plastic containers
    • Glass sterilisation
    • Control of the deep-fryer temperature
    • Boiling processes for jams and pâtés
  • Medical and pharmaceutical industry
    • Sterilisation of surgical equipment
    • Temperature control in laboratories
