| The FHT 59 S
continuously monitors aerosol-bound artificial beta activity concentration in air or
effluent gas. The sampled air is drawn through a filter tape. During deposition, the
aerosol-bound activity is measured by a plastic scintillation detector:
- application in ambient air monitoring networks or stack emissions monitoring systems
- dynamic compensation of varying levels of natural radioactivity in air (Rn-progeny)
- maintenance-free long tern operation by virtue of highly-reliable step filter mechanics
- direct read-out of measured values in physical units of Bq/m³
- easy systems integration via RS232 serial interface
- LAN coupling optionally available
