The FHT 59 E continuously monitors beta emitting noble gases
in workplace or effluent air. The sampled air is drawn through a measuring vessel with the
emitted radiation being detected by two large area proportional counter tubes.
application in workplace or stack emissions monitoring systems
calibration factors for Kr-85 and Xe-133 available
no gas supply required by virtue of sealed proportional counter tubes
maintenance-free long term operation
direct read-out of measured values in physical units of Bq/m3
easy systems integration via RS232 serial interface
LAN coupling optionally available
