Model 202紫外臭氧分析仪Ozone Monitor

Model 202紫外臭氧分析仪Ozone Monitor 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
   

Flash card memory is now provided standard on the Model 202 Ozone Monitor.

The Model 202 has been designated by the EPA as a Federal Equivalent Method (FEM): EQOA-0410-190.
