Temperature Mapping & Qualifications

Temperature mapping study and temperature qualification are commonly carried out in Food and Pharmaceutical Industry to provide the Food and Pharmaceutical companies with the confidence that their storage conditions comply with regulatory requirements. A temperature mapping study is carried out to analyze the temperature distribution in a storage area (cold storage box, refrigerated trucks, refrigerators, cold rooms, warehouses, etc.) and determine whether the temperature inside the storage area is always maintain between the desired temperature.

Usually the display will show the current temperature, however

  • How about the various shelves and corners of the cold room where you are keeping your products which are far away from sensor?
  • How can you verify the temperature of the cold chain can be maintained at a period of time if there is a power failure?
  • How do you know about the variations when a door is opened?

Here at Testo we want to help better control and validate your Controlled Temperature Units (CTU’s), warehouses, and facilities. Testo offers different solutions to help complete validation mapping of each chamber or area within each facility with the help of Testo’s compact and robust line of data loggers coupled with 21 CFR Part 11 compliant software. Our specialist not only can provide you a solution, but also can advise on your needs.
