Low power consumption version (SA210) for emergency systems

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)
