SURISA offers a wide range of products which experience a change in colour when temperature varies. These products can be classified in three main types of product:
Thermosensitive reversible strips
These indicators show the current temperature in colour. They are made up of liquid crystal which calibrated on different temperatures and printed over auto-adhesive paper act as a normal thermometer. Temperature is shown with a intense green colour over the black background. Our thermometers are different form the "usual thermometer" because as they are printed on paper they have a high flexibility which makes them perfect for usage over curved surfaces. The technology used is based on the BS EN ISO 9001 quality standard. We frequently name these thermometers reversible strips to not confuse them with the irreversible strips.

TEMPSAFE, security device. Visit our link to get more information.
Liquid crystal suffers a secuential colour change brown / green / blue, as temperature varies, where green indicates real temperature. With a +/- 1ºC accuracy (0,5 in medical usage thermometers).
Variables such as colour intensity, durability/stability, sensitivity and response time can be controlled to produce different types of meters depending on the requirements. Aswell as shapes: Round, squared, rectangular... Products can also have non uniform shapes(such as flowers, animals etc..)
Our 20 year experience dealing with liquid crystal allows us to offer our customers not only a wide range of default thermometers, but also a range of possibilities to create Custom Thermometers.
- Available range of temperatures using liquid crystal: from -30ºC to +90ºC (*)
- Increments using liquid crystal: 1ºC to 10ºC
- (*) Our research department is working on reaching temperatures up to 120ºC without losing on product durability. At the moment we have reached such temperatures but the product has a shorter life span. We currently offer some products which reach that temperature
Thermosensitive inks
Thermosensitive Inks are used to create many types of product due to their behaviour. Mostly applied uses for these are promotional products and their usage in security devices: Money paper, lotterys...
- Temperature range applied to inks: from -10ºC to +70ºC
Promotional products
 |
With our Promotional Products we expand our well known range of liquid crystal thermometers. This new products produced with thermosensitive and photosensitive inks, have as a main feature several colour changes depending on temperature or sunlight (UV).

Irreversible Strips are thermometers which allow to record temperatures in an unasisted way. This indicators have several regions which change colourpermanently when a certain temperature is reached.
Our thermometers are user friendly products, and give an extremely precise temperature reading because they actually read from the surface which has to be checked. In this way we record the required temperature and not the temperature surrounding the product. Being irreversible makes them remain a certain colour when a temperature is reached, which allows the user to see what temperature was reached once the process has finished even if the temperature has changed.
Being strips allows the user to attach them to a report as quality control devices.
Produced based on quality standards BS EN ISO 9001
Types of thermometer
We have a complete range of thermometers varying in shapes and sizes. They can have from 1 to 10 spots of different temperatures per thermometer. Each design has several temperature ranges.
They cover from 29 ºC to 290 ºC, although we also have Low temperature thermometers which cover from -17 ºC to 20 ºC. Other products such as our crayons can measure temperatures up to 600 ºC.
Strips are water, oil, and vapour proof. Their are +/- 1 ºC precise up to 100 ºC and +/- 1 % precise onwards.

Las temperaturas de las etiquetas irreversibles, a diferencia de lo que sucede con los termómetros de cristal líquido, son fijas. Se pueden fabricar sensores "a medida", a partir de una cantidad determinada, pero, eso sí, conteniendo temperaturas de las arriba relacionadas.
Irreversible thermometers catalogue
Special strips
Low temperature
Chillchecker Self-adhesive device, very easy to stick on any packing/surface, due to its small size. Economic and precise, they are suitable to control critical temperatures during the transport and/or product storage.
Tempasure: Sensor that detects the temperature drop to avoid the freezing of materials. Being a sophisticated indicator which uses its own patented and exclusive mechanism, it continues being a self-adhesive device of easy use.
Electronics
Micro temperature indicators: The smallest in our catalogue, ideal for using on diverse electronic components with minimum surface availability.
LIndustrial dishwashers. Sterilization & disinfectant
TDI: It guarantees, by means of a permanent colour change that the washing process has reached the correct temperature. Accepted for its use in accordance to the actual norms of Hygine and Security for which it is recommended as a valid register to include in the HACCP instructions.
Fabrics
Temperature monitoring in the textile industry: Initially designed to control the temperature during the process of fabric fusion its use has been extended to other applications in the textile world. It prevents overheating that would cause fragile fabric appearances, due to insufficient heating during the process of fusion, which would cause a later fragile fabric union/fusion.
