Temperature Mapping is performed to determine if a storage area can maintain temperature within defined limits (Fridges, Freezers, Rooms, Warehouses and Incubators etc.). Sensors are distributed throughout the unit/room in pre-defined locations to confirm it performs within pre-defined set points.
​
The storage area is further challenged with additional tests such as empty mapping, loaded mapping, door open, power failure, pull down tests, fan failure etc. which are all performed to demonstrate the unit controls within pre-defined parameters and to determine the position of permanent monitoring/alarm probes.

It is important to know that different temperature measuring equipment will have different tolerances and response times to changes in temperature. Check that the equipment being used has sufficient accuracy ratings to give reliable data. For example, better equipment will provide readings that are accurate within plus or minus 0.3°C, whereas budget equipment may only have accuracy ratings of within 1.0°C. For products that must be stored within a limited temperature range, this budget equipment cannot provide sufficiently specific temperature assurance.

At Quality Horizons; we are using (±0.3°C, ±3&rH) accurate sensors to detect the lowest trembling in temperature or humidity, so you’ll fully understand the status of your storage area.

Quality Horizons delivers optimized validation by custom designing a protocol for each client to ensure the organization complies with the necessary SFDA, WHO, GMP, GSDP, or Code of Federal Regulations standards. Each custom protocol is reviewed and approved before our technicians arrive on-site, allowing for an efficient, consistent process.

Why is Temperature Mapping Important?

The temperature of different spaces within cooling rooms, industrial fridges and other controlled temperature environments can vary by up to 10°C. Typically, the central space within a chamber will maintain the most constant temperature, while the corners and areas surrounding the fans and access points will fluctuate. There is also external seasonal weather influence to take into account, especially in warehouses.

Temperature mapping is important for businesses and organizations dealing with temperature-sensitive products, like biochemical products such as medications and vaccines, and all kinds of fresh and treated foods, especially fruit and vegetables, frozen foods, dairy and meat products. Verifying that the refrigeration systems maintain an acceptable temperature level for each specific product at all times is what temperature mapping is all about, and this is supported using ongoing monitoring systems.

Once the mapping has ascertained where the points of temperature variation lie within a temperature control system, then monitoring can be installed so that owners and users can prove their adherence to the related health and safety standards. It is also important that any backup systems be rigorously checked, according to the same principle of testing in extreme cases, to be sure that the chambers will work in less-than-ideal circumstances.
