1. Introduction
1.1 Description
The Serinus 10 Ozone Analyser uses Non-Dispersive Ultraviolet (UV) Absorption technology to measure
Ozone to a sensitivity of 0.5 ppb in the range of 0 - 20 ppm.
The U.S. EPA has designated the Serinus 10 Ozone Analyser as an equivalent method and TÜV has
designated it as an EN approved instrument.
This section will describe the specifications of the instrument as well as the main components and
techniques used to obtain stable gas concentration readings.
