    詳細介紹

    美國2B公司的Model 202臭氧分析儀基于成熟的紫外吸收技術@254nm,使測量更加,測量范圍1ppb至100,000ppb(0-100 ppm) 。相對常規儀器,Model 202臭氧分析儀重量輕(2.1 kg),能耗低(12V DC, 0.33 amp,4.0 Watt),因此適合應用于如下場合:

    •    高空測量垂直分布、遙控飛行器RPVS及輕型飛機等場合,在那里對空間及重量有嚴格限制。
    •    需長期檢測的偏遠地區,用電受嚴格限制。
    •    市區地面基站探測網
    •    個人暴露測量,用于環境污染對健康影響的研究
    •    環境健康及安全監測
    •    實驗室研究,研究材料和組織暴露于臭氧的影響

      Model 202臭氧分析儀被EPA認定為等效測量方法(Federal Equivalent Method /FEM:EQOA-0410-190)。作為的FEM,該儀器可廣泛用于各個州和其它檢測機構,遵循大氣質量監督40 CFR 58 節,符合潔凈空氣法則檢測標準。

    • 數據輸入:3 通道,0~2.5 V DC
    • 電源:12 V DC,4.0 W (2.9 W 低功耗模式下)
    • 5種單位顯示,ppm,ppb,pphm,g/Nm3,μg/m3
       

      The 2B Technologies Model 202 Ozone Monitor™ is designed to enable accurate and precise measurements of ozone ranging from low ppb (precision of ~1 ppb) up to 100,000 ppb (0-100 ppm) based on the well established technique of absorption of UV light at 254 nm.  The Model 202 Ozone Monitor™ is light weight (4.7 lb., 2.1 kg.) and has a low power consumption (12V DC, 0.33 amp, 4.0 Watt) relative to conventional instruments and is therefore well suited for applications such as:

    • Vertical profiling using balloons, kites, RPVs and light aircraft where space and weight are highly limited
    • Long-term monitoring at remote locations where power is highly limited
    • Urban arrays of ground-based detectors
    • Personal exposure monitoring for studies of health effects of air pollutants
    • Environmental health and safety monitoring
    • Laboratory studies of the effects of ozone exposure on materials and organisms
    • The Model 202 has been designated by the EPA as a Federal Equivalent Method (FEM): EQOA-0410-190.

      Options

    • Flash Card Memory for virtually unlimited, portable data storage
    • GPS for continuous logging of latitude, longitude and altitude
    • Rechargeable metal hydride battery provides 12 hr of continuous operation
