The report is a comprehensive engineering description of the design, construction details, calibration techniques and operational characteristics of the ozone meter. A complete set of drawings covering the non-standard components such as the detector assembly and calibration unit are available as PB-194 118. The ozone meters utilize a chemiluminescent disc as the basic sensor. When ozone reacts with certain organic compounds, a minute amount of light is emitted; this light is collected and amplified by a photo-multiplier tube. The electrical signal from the PM tube is then a function of the concentration of ozone passing over the chemiluminescent sensor. A description of the chemiluminescent sensor is given; the operational characteristics of the instrument are detailed; and a detailed description of the design and test results for the various sub-assemblies are presented. Various details concerning parts list, installation and maintenance of the instrument, calibration procedures, and operation procedures are included in the respective appendices. (Author)
