Radiometric Air Sampler

High-volume air sampler with automatic regulation of the flow-rate

Air sampling modes:

  • Air sampling at the preset flow-rate (automatic stop after given period of time)
  • Air sampling of the preset volume in m3
  • Air sampling at the preset flow-rate until stopped (manual stop)

NuRMS EGS-40 operates at a principle of centrifugal pump equipped by high-speed asynchronous motor controlled by processor. Especially designed for air sampling through a filter to determine radioactive aerosols concentration in the air. The device does not use commutator motor, so the maintenance requirements are minimal; it can be run in continuous operation. The device is type-approved by the Czech Metrological Institute (ČMI).

Technical parameters:

  • Electrical parameters: 230 V / 50 Hz, power input max. 800 VA, max. current 4 A,
  • Suction power: 5 to 140 m3/h, achievable underpressure at flow rate of 100 m3/h is 12 kPa (new version is being developed with lower flow rates - radioactive iodine measurement),
  • Weight (without filter holder) approx. 13 kgs,
  • Dimensions: width 220 mm, height 300 mm, length 470 mm,
  • Operating temperature range: +5 °C to +40 °C,
  • Standard connection of medium M76x1.5 or by hose with DN 80 mm,
  • Communication interface: USB, RS-232, RS-485, LAN (Ethernet), adjustable impulse output,
  • Connection/communication with PC: supplied SW for Windows (control of air sampling, parameters settings, plots), API in a form of DLL, industrial communication standard MODBUS
