The FHT 59 Si Alpha/Beta Aerosol Monitor features easy systems integration and maintenance-free long term operation. Measurement of aerosol-bound artificial alpha & beta activity concentration is taken from air sampling and conducted by a semiconductor detector. The monitor's step-filter system is highly reliable. The user-machine interface includes FHT 8000 software operable under WindowsTM.
Product Detail
The FHT 59 Si continuously monitors aerosol-bound artificial alpha and 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 semiconductor detector:
Application in ambient air monitoring networks or stack emissions monitoring systems
Discrimination of artificial from natural alpha activity by virtue of an ion-implanted silicon detector
Maintenance-free long term 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
