美國(guó)2B Model 202紫外吸收法臭氧分析儀簡(jiǎn)介:

美國(guó)2B公司的Model 202臭氧分析儀基于成熟的紫外吸收技術(shù)@254nm,使測(cè)量更加精確,測(cè)量范圍1ppb至100,000ppb(0-100 ppm) 。相對(duì)常規(guī)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(yīng)用于如下場(chǎng)合:

  •    高空測(cè)量垂直分布、遙控飛行器RPVS及輕型飛機(jī)等場(chǎng)合,在那里對(duì)空間及重量有嚴(yán)格限制。

  •    需長(zhǎng)期檢測(cè)的偏遠(yuǎn)地區(qū),用電受?chē)?yán)格限制。

  •    市區(qū)地面基站探測(cè)網(wǎng)

  •    個(gè)人暴露測(cè)量,用于環(huán)境污染對(duì)健康影響的研究

  •    環(huán)境健康及安全監(jiān)測(cè)

  •    實(shí)驗(yàn)室研究,研究材料和組織暴露于臭氧的影響

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 250,000 ppb (0-250 ppm) based on the well-established technique of absorption of UV light at 254 nm.  The Model 202 Ozone Monitor? is lightweight (4.7 lb., 2.1 kg.) and has a low power consumption (12V DC, 0.33 amp, 5 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

特點(diǎn):

Model 202臭氧分析儀被EPA認(rèn)定為等效測(cè)量方法(Federal Equivalent Method /FEM:EQOA-0410-190)。作為的FEM,該儀器可廣泛用于各個(gè)州和其它檢測(cè)機(jī)構(gòu),遵循大氣質(zhì)量監(jiān)督40 CFR 58 節(jié),符合潔凈空氣法則檢測(cè)標(biāo)準(zhǔn)。
