- Model 202紫外臭氧分析仪Ozone Monitor
详细信息
品牌：美国2B 型号：Model 202 加工定制：是 分辨率：0.1ppb 测量精度：1.5 ppb or 2% 气体流量：1L/min 基本误差：1.5 ppb or 2% 尺寸：9 x 21 x 29 cm mm 重量：2.5 kg 电源：12VDC Model 202紫外臭氧分析仪Ozone MonitorThe 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
The Model 202 has been designated by the EPA as a Federal Equivalent Method (FEM): EQOA-0410-190.Model 202紫外臭氧分析仪Ozone MonitorOptions
