WarmMark and ColdMark

Simple, precise, economical and easy to apply, WarmMark and ColdMark temperature indicators are capable of recording whenever the temperature goes beyond the previously set minimum or maximum limit, so that you will be promptly warned of any faults in the cooling systems or insulation in containers just upon the arrival of the merchandise.

WarmMark and ColdMark indicators are ideal to control the products that suffer spoilage of their proprieties if exposed to certain temperatures, i.e. :

• Vaccines
• Pharmaceutical products
• Serums
• Insulin
• Laboratory tests
• Temperature-sensible foods (chocolate, pastry…)
• Food with easy deterioration (ex. dairy products and their by-products, fruit, vegetables…).
             The Cold Chain Complete temperature indicator is ideal for respecting the cold chain during the vaccines transport. This double indicator, ascending and descending, controls that producttemperature has been constantly maintained between 2°C and 8°C.




WarmMark and ColdMark temperature indicators have the following properties:

ColdMark: an irreversible change in the color of the liquid contained in these freezing indicators shows whether the product that has been applied on has been exposed to temperatures lower than the response values. ColdMark indicators must be stored above activation temperature up to +110°F/+43°C. 
WarmMark/ WarmMark Duo/ WarmMark Long Run: WarmMark warm temperature indicators, besides indicating whether the temperature has exceeded the set limit, they also inform you of the exposure duration to excessive temperatures, so you can make a more precise assessment as to the possible damage caused to your products during such events. WarmMark, WarmMark Duo and WarmMark Long Run must be stored in an environment with temperatures below the response temperature. WarmMark and ColdMark have a sensitivity margin of +/- 1°C and a useful life of 3 years from the date of production.


Thermax ascendant temperature recording labels offer a highly reliable and irreversible indication of exposure to high temperatures (between 29°C and 290°C). The change of colour on the windows is clear and irreversible in order to indicate the maximum temperature reached. The labels will not de-laminate when removed for reference and can be attached to an inspection report to provide a permanent record. 

Thermax indicators give an immediate response and permanently record the highest temperatures achieved. They are also oil, water and steam resistant. 


Tempasure descendant temperature indicators offer a highly reliable and irreversible indication of exposure to low temperatures. Low temperatures can have detrimental effects on goods like refrigerated pharmaceuticals, foods, chemicals or medical devices. Tempasure temperature indicators clearly show a red window when the product has experienced freezing conditions.  

They are easy to use, to install, to read and guarantee accurate reaction to +/- 2°C in a temperature range available from -20 to +15°C.
