상품정보  

 

라돈 측정기    RAD-7

◈  용   도

  • 건축물 실내 및 지하 생활 공간등의 라돈가스 농도 측정
  • 건축 및 토목 자재의 라돈 방출량 측정
  • 지하수 및 하천수 등의 라돈가스 농도 측정(선택사양)
  • ◈  특   징

    • 단시간 측정 및 연속 장기간 측정 가능
    • 라돈 및 Thoron 측정 및 그래프 출력 가능
    • 1시간 이내에 EPA Action Level인 4pCi/L 측정 가능
    • 빠른 응답 속도와 신속한 영점 조정으로 수분 이내에 재측정 가능
    • 0.2 pCi/L의 고감도 측정 가능
    • 펌프 및 프린터 기본 탑재

    ◈  SPECIFICATIONS

    • Multi-Modes
    Continuous Radon Gas Monitor
    Long-term/short-term screener
    Sniffer, with small tube "snout", to search for radon and thoron entry points
    • Multi-Measurements
    Measures radon in air, soil, and water (with RAD H2O accessory)
    • Sensitivity
    Monitor : 0.4 counts/min/pCi/L
    Sniffer : 0.2 counts/min/pCi/L
    • Range
    0.1 to 20,000 pCi/L
    • Memory
    1,000 previous radon concentrations, and associated data. Can be read out on LCD,
    printed out or downloaded to PC. Also shows high, low, average and standard
    deviation of readings
    • Principle of Operation
    Electrostatic collection of alpha-emitters with spectral analysis
    • Built-in Air Pump
    Nominal 1ℓ/min flow rate. Inlet air filter. Inlet and outlet air connectors
    • Spectrum Readout
    Pulse height spectrum of alpha distribution verifies radon/thoron, and also shows the RAD7 is operating properly. Accurate determination of the alpha particle energies produces a radon signature that allows discrimination of radon and thron's alpha particles from those of other isotopes
    • Fast Low-Levle Readings
    In continuous monitor mode, RAD7 measures the EPA action level of 4 pCi/L in just
    1 hour(60 minutes), with standard deviation of 10%. Since the RAD7 has virtually no
    background, it is much more sensitive than other electronic detectors, easily
    measuring down to 0.1 pCi/L
    • Recovery in Minutes
    Recovers from high radon exposure with a 3.05 minute half-life : to less than 10% of
    peak value in 12 minutes ; to less than 1% of peak value in 30 minutes. Drops from
    20,000 to 1 pCi/L in less than an hour
    • Tamper Proof
    A "Test Lock" command is programmed into the machine to secure your RAD7
    against all kinds of intentional or unintentional tampering
    • Auto Mode
    This setting starts a test run in SNIFF mode, then switches to NORMAL mode after
    the first 3 hours. No more waiting for equilibrium. Gives quick response, followed by
    statistical precision
    • Continuous Updating
    Gives continuous update of radon levels so you can see the trend at all times, not
    just at pre-set intervals
    • Computer LCD Display
    2 line ×16 character, alpha-numeric. easy to read
    • Audible Radon Count
    Indicates presence and intensity of radon and thoron. May be turned on or off
    • Power
    AC/battery powered - 5 AH 6V batteries. Automatic charge when plugged in.
    Continuous battery operation : 24 hours sniffing : 72 hours continuous monitoring
    • Printer
    Hewlett-Packard Model HP 82240A
    • RS-232 Port
    Computer or modem hookup
    • Operating Range
    Temperature : 5°∼40℃
    Humidity : 0∼100%, non-condensing
    • Weight/Size
    4.9kg - 24×19×27cm
    • Case Material
    High density polyethylene

    ◈  OPTIONAL ACCESSORIES

    • RAD H2O water Accessory
    1 set
    • Remote control software
    1 set
