  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
• 
  Time and temperature indicators
  The indicator technology for time and temperature control is aimed at products that deteriorate when subjected to critical temperatures for a certain period of time. This is the case with vaccines, medicines, and most food products. The record of the time and temperature in which they have been kept is the guarantee that they are in perfect condition for use. These labels allow temperature control in shipments and storage, in an economical and simple way. Its low cost allows the control of the preservation conditions of vaccines and food to be carried out directly on the boxes. This allows a very high level of control and greater security in compliance with the cold chain.
  

  Operation of time and temperature control labels

  These indicators contain three control points, which when subjected to a temperature higher than that marked on the label, change color progressively. The points are calibrated for specific periods of time, for example 2 hours, 12 hours and 48 hours. Thus, depending on the time that has elapsed, during which the product is subjected to an inappropriate temperature, each of the points will successively change its color from white to red, first the first point, then the second and finally the third.
  
  This change in color of each point is cumulative, that is, it adds the periods of overheating of the product, even if these occur intermittently. In other words, if the temperature is returned to the right conditions, the color change stops and only resumes if we expose the indicator to a temperature higher than the established temperature.
  
  The change is permanent and irreversible, so that it is possible to know a posteriori whether the appropriate temperature conditions have been maintained, and if not, what the overexposure period has been.
  Some of the indicators contain a single point of control, instead of three. In this case, the operation of the label is the same, except with a single point, which will be activated when the temperature is exceeded during the established period of time.

  
  
  

  Advantages of time and temperature indicators

  • Easy to use and interpret by non-technical personnel
  • Low cost
  • They do not use batteries or have products that harm the environment
  • They monitor the temperature and also the exposure time
  • They can individually control the product if necessary
  • As they are irreversible, they ensure that the temperature conditions in transport and handling have been met.

  Buy time and temperature labels

  
  The recording of time and temperature, using adhesive labels, is a practical and efficient means that complements dataloggers and temperature recorders. These indicators, due to their low cost and ease of adhering them to the product or smaller containers, allow monitoring the actual temperature that the product receives. In the event of a malfunction of the cold room or negligence in the transport of the merchandise, it provides us with information on which containers or products have been affected and which have not. Buying temperature indicators is saving costs and increasing safety.
