Everything under control
The clean room is finished, all plants and systems are in operation, production can start. Beforehand, however, numerous acceptance measurements are necessary in order to prove to both the responsible authorities and your customers that the acceptance limits of the respective specifications are met.

According to VDI 2083, DIN EN ISO 14644 and EU-GMP, these measurements must be repeated at regular intervals. And we will take care of this for you:
First, we examine all terminal filters for visible damage. Then, we use state-of-the-art measuring equipment to record important parameters such as particle concentrations and germ counts, air velocity and air volume flow, room differential pressure and filter differential pressure, temperature and humidity, recovery time and clean-up phase or sound pressure level and illuminance.
In addition to checking the actual room conditions, we can also carry out measurements according to ISO 8573 on a large number of high-purity gases. Our own measuring system enables us to determine various parameters such as the particle concentration and air germ count, the pressure dew point, or the residual oil or residual oxygen content.
But we do not just leave it at measurements alone. Because it goes without saying that we also get to the bottom of any deviations, analyze the causes and search for optimization and solutions. In dialogue with you - building on our many years of experience.
The measure of things
Accuracy and exact measured values are the key factors in cleanrooms. The equipment required for the various control mechanisms must provide correct measurement results which can only be guaranteed by checking their functionality at recurring intervals. For your own confidence and that of your customers.

If you want to permanently rely on the measured values of your instruments, you have no choice but to have them calibrated regularly.
Whether hand-held measuring instruments or built-in sensors: We at CAT Clean Air Technology GmbH calibrate your probes either in our own laboratory or at your site in certified quality according to DIN EN ISO 9001:2015. We will also be happy to advise you on sensible calibration cycles adapted to your intended use.
You can count on us: We ensure that your measured values are correct in terms of temperature, pressure, relative humidity, flow velocity or particle count. Because we have always calibrated our own equipment in the CAT laboratory – an experience you can rely on.
For this purpose, measuring equipment is used whose reference is traceable to the so-called National Standards of the Physikalisch-Technische Bundesanstalt (PTB). The calibration of these DKD reference instruments is in turn carried out by external accredited calibration laboratories.
