Air Monitors
Model 334A
Order Part Number: 48-3859
  • Portable alpha continuous air monitor
  • Weighs 5.9 lbs
  • ​Uses alpha peak-shape-fitting for individual measurements of nuclide counts–significantly reducing false alarms
  • Performs both fast-responding (Acute) and high-sensitivity (Chronic) measurements
  • ​Acute and Chronic dose, concentration, and flow logging as well as spectrum logging
  • Wireless 802.11b RadNet Output Option for remote monitoring
  • Typical sensitivity of 1.0 DAC-h (Chronic) and 30 DAC-h (Acute) with less than one false alarm per 2080 hours of operation
  • Radon Mode Option displays PAEC and also indicates radon progeny equilibrium
