SA – Air Monitoring station
The SA environmental monitor is used for continuous measurement of aerosol activities in all gaseous effluents. It can be fully integrated into environmental radiation monitoring systems.
The SA air monitoring station is designed to complete gamma radiation monitoring systems in environment networks, where continuous monitoring of the particulate with nuclide identification is required.
It combines β & γ aerosol activites and spectrum measurement within the environment. The station aimed at monitoring outdoor particulate activities as part of a national or regional environment network, around nuclear facilities and nuclear sites.
The SA sation is existing in 2 versions:
- The SA 200 version is equipped with a strong pump system allowing a high air flow rate for very accurate measurements.
- The SA 210 version is designed for situations requiring autonomous monitoring autonomous from main supply. It has a low power pump incl. battery pack modules, and performing a lower flow rate.

- The SA air monitoring station is used for continuous measurement in all gaseous effluents of particulate volumetric activity.
- The sample is pulled by means of a pumping unit (3m³/h or 17m³/h flow rate according to versions) and then transferred to a detection assembly.
- The monitor, based on an embedded low power industrial computer, calculates the measured volumetric activity and triggers alarms whenever preset threshold levels are exceeded.
- A SpectroTRACER probe can be optionally placed on the top of the monitor to allow both gamma dose rate and measurements and noble gas monitoring.
For SA200 version:
- SA 200: beta and gamma particulate
- SA200-NG: beta and gamma, noble gas volumetric activity and gamma dose rate (with additional SpectroTRACER NaI(Tl))
- Optional heating and ventilation kit
- Sampling line extension
For SA210 version:
- SA 210: beta and gamma particulate activity
- SA 210-I: beta and gamma particulate activity (with specific charcoal filter)
- SA210-ING: beta and gamma particulate, noble gas volumetric activity and γ dose rate (with additional SpectroTRACER NaI(Tl) and specific filter)
