In addition to specifications and recommendations regarding particle size and concentration in accordance with DIN EN ISO 14644 and VDI 2083 Sheet 3, cleanrooms must fulfil various guidelines, such as the humidity content in the ambient air.

Measuring the relative humidity of the room air is essential to ensure a stable and constant climate during the production of sensitive products. Alongside other parameters, it is one of the standard parameters for constant air quality in cleanrooms.

Various medicines and vaccines, among other things, are very sensitive to excessive relative humidity. Here it is not only important not to exceed a certain threshold value in terms of relative humidity, the Humidity must also be kept at a constant level in order to always be able to guarantee the same quality of the goods produced.

CS residual humidity sensors not only measure the humidity content in the compressed air line safely and reliably, they can also measure reliably in the room and display several other humidity parameters such as relative humidity [%rh], absolute humidity [^g/m3], the Degree of humidity [g/kg] or the Humidity fraction [PPM] in addition to the Dew point.

The particle concentration in the supply air of the cleanroom can also be checked and monitored using a Particle counter. Special specifications apply here with regard to the size and concentration of the Particles.

CS INSTRUMENTS also offers you the ideal measuring devices for checking the conditions in the cleanroom.
