The MLM Measuring System has been developed in order to guarantee the functionality of ventilation systems by conducting airtightness tests of the duct system.
It is also suitable for testing building components as well as small and highly airtight clean rooms.

This robust spraying system has been developed for mobile use at construction sites and creates a steady, closed film of water to simulate driving rain on building envelopes.
