Immission monitoring

In emission monitoring of power plants, cement plants, and other industrial facilities, continuous emission monitoring systems (CEMS) are employed.

Ambient air monitoring

Various sensors and analyzers are used for monitoring ambient air quality. These are adjusted to the very low concentrations to be measured using a HovaCAL.

The HovaCAL N SP can both heavily dilute dry test gases and evaporate organic solvents and aqueous solutions to generate precise calibration gases in the ppm and ppb range. It is also able to adjust a relative humidity, as in the ambient air.

The HovaGAS is able to generate precise calibration gases from dry test gases in the ppm and ppb range.
