FPI AQMS-650 measures NH₃ in the ambient air, which delivers a stable and precise value. It adopts chemiluminescence technology with an external converter that can combine its use with AQMS-600 measuring NOx; during the measurement, NH₃ will be converted into NO by oxidation. And it also comes with its own developed software. The remote PC software allows for a remote connection with a virtual interface and data downloading capability to operate the software.
