Freezer temperature-indicating stick

Standard safe packing

  CRYOmark™ is single-use ultra low temperature-indicating stick which irreversibly change its color from white to red by reaching or exceeding color changing temperature. It is especially designed for freezing temperature monitoring such as freezer temperature and cold chain logistic monitoring.  

 Detect and signals abnormal temperature rise happened under refrigeration and freezing temperature by color change.

• Color Change Temperature: -20 °c to 9°c

• Store temperature: ambient temperature

• Simple activation method even under refrigerated environment

• Easy to use

Activation Method   

1.   Prior to use, CRYOmarker should be precooled below predetermined temperature for predetermined time.

       - Color change temperature is +9, -4 and -10 °C : Should be precooled at least for 12 hours below -18 °C.

       - Color change temperature is -20 C°: Should be precooled at least for 12 hours below -40 °C.

2 .  To activate CRYOmarker, bend it lightly once until you hear snapping sound and feel light shock, with gloves on. CRYOmarker starts monitoring temperature.

3.  Set where temperature monitoring is required.

4  CRYOmarker changes its color from white to red to indicate temperature rise. When more than half area of a CRYOmarker is reddened, Temperarure Limit EXCEED.

 ♦ Shock of Bending activation may cause faintly redden CRYOmarker. However, this does not mean temperature Limit EXCEED.

Usage Example  

• Refrigerated and freezing temperature control during transportation and storage. (Ex. Freezer, Chilled Container, Pharmaceutical products, Chemical products and Frozen food)  
• Enhance quality assurance. Differentiation from competitor.
• Increase customer’s satisfaction and reliability of your product.
• Reminder for driver.

About us

"From the Ocean to Outer Space"

  NiGK Corporation was fully financed and established by NOF CORPORATION in December 1980. Inheriting the know-how accumulated by TEIKOKU PYROTECHNICS MANUFACTURE CO., LTD., which had lasted from 1938 to 1970, and that of NOF CORPORATION, Kawagoe Plant which succeeded it, we have promoted research and development in various fields in parallel with manufacturing of pyrotechnics and temperature indicating materials and other products. 

  With on ever-expanding scope of our business, our products have been patronized in different fields widely ranging from the deep seabed to outer space, as indicated by our catch phrase, ""From the Ocean to Outer Space,"" contributing to safety and reliability of various systems.

  In order to not only swiftly respond to ever-advancing needs and supply useful products to society, but also ensure safety and reliability, we would like to fulfill social responsibilities as a technology developing corporation and move forward to materialize further development.
