SCOPE OF MAINTENANCE
What we see with every
Check maintenance
Every maintenance procedure follows a standardized test protocol – for maximum reliability of your system.
01
Calibration according to ISO 21501-4
Testing your particle counter according to the international standard for light-scattering particle counters – the basis for valid measurement results.
04
Counting efficiency &
Zero count rate
Functional testing of all input/output nodes in the system. Verification of signal transmission from sensors to the software.
02
Counting volume & flow rate
Uninterruptible power supply testing – to ensure your system continues to operate seamlessly even during power outages and no data is lost.
05
Functional and visual inspection
Comprehensive functional testing of all installed sensors. Verification of the measured values for plausibility and accuracy.
03
Size classification
Testing all alarm lights and alert functions. Ensuring that limit violations are reliably reported – via email, SMS or visually.
06
Traceable certificate
Maintenance and testing of all vacuum pumps for particle counters. Hose inspection and flow verification for reliable particle measurement.

FREQUENTLY ASKED QUESTIONS
FAQ – Calibration
& Mapping
What is an SCS-accredited calibration?
An SCS-accredited calibration (Swiss Calibration Service) guarantees the internationally recognized traceability of your measurement results to national standards. vali.sys performs calibrations using SCS- and DKD-certified reference instruments – proof of quality at the highest level.

How often should cleanroom sensors be calibrated?
Calibration intervals depend on the standard and the application. In GMP-regulated environments, annual calibrations are standard. Depending on the sensor type and usage, shorter intervals may be advisable. We will advise you individually.
Does vali.sys offer on-site calibrations?
Yes, we offer both on-site calibrations directly in your cleanroom and calibrations in our certified laboratory in Bubikon. On-site calibration minimizes downtime and allows testing under real-world conditions.
Which standards are adhered to during calibration?
Our calibrations are performed according to ISO 17025, GMP (EU/FDA), ISO 14644, and industry-specific guidelines. Each calibration certificate contains all relevant information regarding measurement uncertainty and traceability.
