Dust frequently poses a negative environmental condition. This also applies to work carried out in a field or at a construction site, for example.

This is why we thoroughly test our products for their dust-sealing properties. During this quality test, unfired Portland cement is used as a test medium. The test is optionally performed in sample function operation, and with overpressure or underpressure exposure of the device under test. The test is assessed by measuring the photometric value before and after the test. Only those products that meet all requirements receive internal quality approval.
