Clarity - Ozone Module
The Clarity Ozone Module is based on best-in-class technology from 2B Technologies, and provides accurate measurements of ozone in air over a wide dynamic range extending from a few parts-per-billion by volume (ppb) to an upper limit of 100 parts-per-million (ppm) based on the well-established technique of absorption of ultraviolet light at 254 nm.
Product Details
The Ozone Module integrates seamlessly into Clarity networks with an ozone monitoring technology has been approved by the U.S. Environmental Protection Agency as a modification of Federal Equivalent Method (FEM): EQOA-0914-218. The Ozone Module is well suited for use by states and other monitoring agencies under 40 CFR Part 58, Ambient Air Quality Surveillance, for monitoring for compliance with the Clean Air Act.
