Thermal process validation, flow visualization, and
cleanroom certification & qualification
*This service is offered only in Switzerland and Austria *
Many years of experience and well-trained technicians make Particle Measuring Systems (Switzerland/Austria) your partner for cleanroom qualification and thermal process validation. We support you in ensuring patient safety, whether by checking the limit values of your cleanroom or validating your sterilization processes.
Our test reports are documented in accordance with all applicable guidelines and specifications and are preferably created digitally. We can also take individual customer requirements into account.

THERMAL PROCESS QUALIFICATION
Our highly qualified and experienced thermal validation team uses high precision measurement systems to perform thermal process evaluations according to your requirements. Our advanced practical knowledge allows us to meet your needs, whether you require ongoing routine thermal validation or project support.
CLEANROOM CERTIFICATION AND QUALIFICATION
We offer full cleanroom certification and qualification for all cleanroom classes based on applicable standards:
- ISO 14644
- EU GMP Annex 1
- VDI 2083


FLOW VISUALIZATION
Our team can perform on-site flow visualization to help you visualize, understand and improve existing airflows. Our team of experts will help you identify problems to ensure quality.
Calibration of anemometers and volumetric flow hoods

Calibration of anemometers
In order to be able to measure air velocities in clean rooms reliably and accurately with an anemometer, periodic calibration of the anemometer is essential. This is the only way to ensure that the measured air velocity values correspond to reality. With our specially developed and built wind tunnel, we can calibrate your anemometer in an air velocity range of 0 to 40 m/s – regardless of design and manufacturer. The SCS calibration certificates (ISO 17025 accreditation) issued by us fulfill all requirements, especially the requirements from the GMP area.

Calibration of volumetric flow measuring hoods
In cleanrooms and similar applications, the precise measurement of supply or exhaust air volume flows is essential, for example to determine the air exchange rate. This is only possible with precise – i.e. calibrated – measuring devices. Our specially developed and built volumetric flow test stand allows the calibration of volumetric flow measuring hoods (balometers) in a measuring range of 50 to 1900 m³/h. The SCS calibration certificates (ISO 17025 accreditation) issued by us fulfill all requirements, especially the requirements from the GMP area.
