a blotter toclearly indicate the duration of the exposure.


Specification of  Warmmark

Size1.9cm W x 4.6cm Lx 0.15 cm thickness
Storage ConditionUnused product must be stored in an environment with temperatures below the response temperature for optimal shelf life
Temp. range-18°C/0°F,5°C/41°F,8°C/46°F,10°C/50°F,20°C/68°F,25°C/77°F,30°C/86°F,37°C/99°F
Temperature Accuracy +/- 1°C / +2°F
Packing10pcs/bag,100pcs/big bag, packed in hermetic bag out of which indicates product name and quantity.
Expiration Date2 years from date of manufacture  
Use range It can monitor whether good exposure in the inappropriate temperature environment and records whether the temperature is rational during shipping. And the original unqualified temperature record will not change as the temperature and time change. So it is usually used on medical supplies, vaccine, blood/plasma, capsule products, chemicals, chocolate, freeze/refrigerated food, etc.
How to use

Please tear the transparent liner behind the label, and then stick the whole label on a dry flat place. If it is exposed in the temperature that above its activation temperature, chemical things inside will start to melt and flow. Thus color in window will indicate within a controllable data. When temperature drops under its activation temperature, the chemical things stop to run. (Accuracy of warmmak label can be guaranteed within +1°C)


Working principle

If this label is exposed in the temperature environment that higher than its reactive temperature, chemical things inside of it will turn to red and start to flow along with inside tube. It has 3 round windows, it takes some time when chemical things flow to every window. Thus, time of turning red can be calculated. Chart below will show that. (The time below refers to the time when the labels are exposed in its activation temperature more than 2°C and then all window change color completely)
