MicroLite Solution - Monitoring Temperature and Humidity during Production of Veterinary Products


Veterinary products must be manufactured in accordance with the principles and guidelines of good manufacturing practice. Manufacturers must set up an effective quality assurance system and production must be carried out in accordance with good manufacturing practice and follow the pre-established instructions and procedures. Technical measures must be taken in order to avoid, in particular, cross-contamination.

Application: Production of Veterinary Products 

Organization: Veterinary Products  Manufacturer

 

Background:

Veterinary products must be manufactured in accordance with the principles and guidelines of good manufacturing practice. Manufacturers must set up an effective quality assurance system and production must be carried out in accordance with good manufacturing practice and follow the pre-established instructions and procedures. Technical measures must be taken in order to avoid, in particular, cross-contamination.

 

About the Customer:

 

A leading European manufacturer of Veterinary Products has established a validation group for internal qualification of all thermally controlled equipment ie: refrigerators, freezers, chilled storage, incubators, walk-in chambers and thermostats. 

 

Key Customer Challenges:

  

During the commission of a new thermostation room the customer found that the heat distribution did not conform to requirements.  The lower positions inside were colder than the higher ones and air circulation had to be immediately reconsidered to avoid production failures. These changes were established by altering the air inlet and exhaust anemostats. For the qualification and testing of these changes the Microlite logger was successfully used.

 

MicroLite Implementation:

 

12 temperature loggers plus 1 temperature and humidity logger of the Microlite product range were installed in the thermostation room for thermal mapping of each chamber. Simultaneously, 15 loggers were used for further processing, investigation and trend analysis. The sampling rate for thermal mapping of each chamber was set for a week long period with 1 minute intervals. 

 

Measurable Results:

 

The independence of the stand-alone MicroLite loggers allowed the customer to position the loggers without the wired constraints of thermocouple based equipment. It was very easy to hang the loggers on shelves or to use the cradle for wall-mounting and even put them into closed chamber ovens without having the difficulty of leading the thermocouple wires out of the equipment. 

 

Data download is fast through the USB interface of the MicroLite Solution and can be even faster using a USB hub. Data is selectable for evaluation from the database from/to the exact time and unnecessary data can be easily cut from the beginning and the end, thus only important data is further processed. 

 

Accuracy levels are extremely high at 0.3°C and the memory capacity is large enough for the thermal mapping process of a chamber, for even for a week long period with 1 minute intervals. Data was simultaneously exported from the additional 15 loggers, using the DataSuite software directly to an Excel datasheet for further processing, trend analysis and so on.
