Clarity Collaborates with 2B Technologies on Ozone Module
   Add-on Module for Clarity Networks Expands Capability to Include FEM-quality Ozone Measurement

BERKELEY, Calif., October 12, 2021 -- Clarity Movement Co. today announced its collaboration with 2B Technologies to create a custom ozone add-on module for Clarity air quality monitoring networks.

The Ozone Module integrates seamlessly into a Clarity network using the new Node-S 2, Clarity's second-generation hardware component of its complete air quality monitoring solution (see related release, dated today).

The new Ozone Module uses the "Federal Equivalent Method" for customers in areas with ozone attainment goals in the United States. Together, a Clarity network with an Ozone Module enables continuous monitoring of these pollutants, for accurate data in a fully supported, worry-free environment.

"Ground-level ozone has such a significant impact on health, we simply had to make it a top priority for one of Clarity's very first add-on modules," explained David Lu, CEO of Clarity Movement Co. "We are thrilled to collaborate with 2B Technologies, known worldwide for instrumentation accuracy, in small devices that use less power. The new Ozone Module can seamlessly integrate into our scalable monitoring networks using the new Clarity Node-S 2, giving our customers more flexibility than ever before."

"Working together to add FEM-quality ozone monitoring to Clarity’s offerings is an exciting and natural fit for 2B Technologies,” said Jessa Ellenburg, P.E., director of educational outreach at 2B Technologies Inc. “We chose to collaborate with Clarity because of their high quality data infrastructure and their reputation for strong customer service. Clarity’s focus combines well with 2B Technologies’ 20+ years of ozone monitor development and public involvement in air monitoring.”

The Ozone Module 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.

The underlying 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.  

Clarity's Complete Solution

Clarity is transforming air quality measurement. Each Clarity solution provides everything needed -- hardware, software and expert services -- in a complete and scalable package. Customers get continuous monitoring for accurate, calibrated data in a fully supported, worry-free environment.

At the heart of the solution is the Clarity Node-S. Using solar power and built-in cellular connectivity, Clarity Nodes take only minutes to install. Once activated, they transmit PM2.5 and NO2 raw data instantly. Clarity Nodes also support add-on modules for wind, ozone and black carbon measurement to bring even more flexibility at greater scale. The raw data is calibrated using proprietary models developed by our air quality experts to ensure high accuracy.

Clarity solutions include the software tools used for remote calibration, sensor network management, data analysis, data visualization and data sharing. The calibrated data are available in real-time through the comprehensive, intuitive Clarity Dashboard as well as programmatically via RESTful APIs, and can be publicly shared with the Clarity OpenMap.

Dedicated Clarity experts provide all the know-how, training and support a customer needs to use the tools and understand the resulting data. Governments, businesses, schools and community groups in more than 60 countries worldwide use Clarity's highly-accurate air quality data to make informed, critical decisions.
