Beskrivelse av artikkelen

Probe for Radon Concentration Measurement in buildings with Wireless and USB data transmission

  • New generation of portable radon probe
  • Standalone measurement with saving data into own internal memory
  • Direct USB connection of probe and a PC
  • Wireless data transmission via wireless Central Unit
  • Internal high-capacity rechargeable accumulator;
    USB charging or power adapter 230V/50Hz
  • Probe measurement possible to turn off by switch while real time in probe keeps on
  • Diagnostic LED diodes ´charging´ and ´status´
  • Display and button for quick result viewing (TSR3D)

Measurement

  • Continuous monitor of radon volume activity – radon concentration electronic measuring 20 - 1M Bq/m3
  • Current radon concentrations – short-term (hourly average) and long-term (daily average)
  • Measurement uncertainty – < 13% at 300 Bq/m3 per 1 hour; < 3% at 300 Bq/m3 per 24 hour
  • Measuring algorithm – Calculation from RaA or from RaA +RaC impulses
  • Accompanying measurements – temperature (-20 ° C to + 60 ° C), humidity (10% - 90%), energy spectrum
  • Long-term records – results stored in internal memory for the period up to 150 days, export for spreadsheet

Data

  • USB interface – data are downloaded directly via USB into PC
  • Wireless interface –data are downloaded wirelessly via Central Unit (supplied extra)
  • PC application – data managing, viewing, export and system configuration by PC application

Advantages

  • High Mobility – Portable device – easy equipment transfer between locations
  • Nondestructive Installation – Internal accumulator with battery life more than 1 year without charging
  • Autonomous Measuring – Each probe separately measures and stores data into internal memory
  • Data Download Options – Continuously or one-time after measurement end
  • Wireless Network – Up to 16 elements with one central unit
  • Wireless Range – Can be increased by repeaters
  • Technical Support – Extensive services directly from manufacturer
