The FHT 59 S Alpha/Beta Aerosol Monitor features easy systems integration and maintenance-free long term operation. Measurement of artificial beta activity is taken from air sampling, and detection is made possible by a plastic scintillation detector. The monitor's step-filter system is highly reliable.
Product Detail
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
Features
Measuring range for artificial beta aerosols 0.3 Bq/m3 - 0.5 x 106 Bq/m3
ZnS coated plastic scintillation detector
Measuring electronics FHT 8000 operable under Windows
