Cleanroom monitoring reduced to the essentials

With the monitoring system vali.lite you are perfectly equipped. We invented a system that suits small budgets and is technically up to date and provides you with all required data. The evaluation features are reduced to the essentials and thus offer companies with a small investment budget an excellent and reliable monitoring solution.

vali.lite in operation



A monitoring system for a cleanroom facility usually includes:

  • Network-compatible PC system with USP, printer, etc.
  • Switch cabinet and/or control unit for acquisition and output of analogue and/or digital signals
  • Environmental sensors and measuring amplifiers
  • Particle counters with isokinetic sample probe
  • Software and tools



The reduced enVigil software of our monitoring system runs on Microsoft Windows.

The following cleanroom parameters are monitored and documented:

  • Cleanroom classification (particles and germs)
  • Humidity
  • Temperature
  • Differential pressure and air velocity underneath the filters

The intervals of verification measurements vary depending on the cleanroom classification.

In contrast to vali.mon, vali.lite does not allow to create different interfaces. Furthermore, the lite version uses a standardized documentation.
