FHT 59 N
Nuclide Specific Aerosol Monitor

The FHT 59 N1/NE1 continuously monitors aerosol-bound gamma activity concentration in air or effluent gas:

• application in ambient air monitoring networks or stack emissions monitoring systems

• nuclide-specific detection of gamma emitting isotopes

• maintenance free long term operation by virtue of a highly reliable step-filter mechanics

• spectrometric analysis with evaluation of the activity concentration of each identified nuclide in units of Bq/m³

• LAN coupling optionally available

Features

  10 mBq/m³ - 100 mBq/m³ after 24h
• HPGe detector in vertical dipstick geometry
• refrigerator version optionally available
• PC based multichannel hardware
• online monitoring software operable under windows NT
• low noise maintenance free gas ring vacuum pump;
  air flow app. 10 m³/h
