2BTech-202 Ozone

2BTech-202 Ozone Single Beam

The Model 202 Ozone Monitor is designed to enable accurate and precise (±1.5 ppb) measurements of ozone ranging from a few ppb to 100,000 ppb (0-100 ppm) based on the well established technique of UV absorbance at 254 nm. The Model 202 is light weight (2.1 kg.) and has a power consumption of only 4 watts. The Model 202 has been certified by the EPA as a Federal Equivalent Method (FEM): EQOA-0410-190  The Model 202 has been used for the past decade in ozone monitoring networks of the U.S. National Park Service and National Forest Service. It also is widely used by NOAA, EPA, Environment Canada and the British Antarctic Survey for studies of ground-level ozone.
