Vacuum calibration from high vacuum and to atmospheric pressure makes our laboratory unique in Denmark. This benefits the Danish industry, as knowledge and resources are retained in Denmark.

Competitive measuring range within vacuum

Our vacuum laboratory in Brøndby is accredited by DANAK for its wide measuring range within vacuum calibration. It covers an absolute pressure from 10μPa to atmospheric pressure, with an uncertainty down to 6μPa in the high vacuum range, and between 0,005 - 0,30% in the low and medium vacuum range.

The measuring range is thereby unique in Denmark, but with the accreditation, the laboratory obtains direct traceability to the international primary standard in Germany, making it competitive with foreign laboratories. 

Vacuum is in high demand in pharmaceutical and food industries

Vacuum gauges are most often used in freeze-drying processes.

In a freeze-drying process, pharmaceutical or food products are subjected to extremely low pressure in a freeze-drying cabinet, to extract the water from the product. The product is transformed into a dry state, with the potential to be powdered for medicinal or other use.

In a freeze-drying process, it is necessary to control the pressure of the freeze-drying cabinet, to make sure the products are freeze-dried correctly, which requires vacuum gauges calibrated in a wide range. As many freeze-drying processes take place at high vacuum, the extension of the measuring range is a much-appreciated development, as vacuum gauges can now be calibrated under the conditions corresponding to the industrial laboratories.

Kurt Jørgensen, who oversees calibrations at the Danish pharmaceutical company, Chr. Hansen, states:

“The new measuring equipment for vacuum at FORCE Technology gives a higher degree of precision in the calibration process, and thus a higher assurance of the precision in our production processes. Furthermore, the flexibility in completing tasks is increased by the fact that we can get the gauges calibrated locally, as the turnaround times can be kept down.”

Unique national standard

The wide measuring range and the DAKAK accreditation provide a unique national competence which strengthens Danish knowledge in the area, both academically and commercially – from which the Danish industry will benefit.

Academically, Denmark can now respond to a growing demand for knowledge in the field of vacuum calibration, and transfer it to the pharmaceutical and food industries in particular, but also to educational institutions and the manufacturing industry.

Furthermore, the calibration of vacuum gauges and working standards will become easier and quicker, as the calibration can be performed within Denmark’s borders instead of being sent abroad.

In the vacuum laboratory at FORCE Technology, we calibrate vacuum from atmospheric pressure and down to 10μPa.
Calibration of a vacuum gauge is performed directly by comparison with one or more reference standards to achieve the lowest uncertainty. Calibration takes place in an arrangement consisting of a calibration chamber servings as a common medium for the reference gauges and units under calibration, several working- and reference standards, pumps for the evacuation of the chamber, and a gas regulation system to regulate the vacuum in the chamber.
