Gas Phase Ozone Concentration Comparisons From a Commercial UV Meter and KI Wet-Chemistry Tests

Abstract

Abstract Abstract Formal ozone system power-production tests conducted at ten (10) different ozone installations have resulted in over 100 comparative UV meter versus KI wet-chemistry ozone concentration tests for fifteen (15) individual UV meters. The wet-chemistry tests were conducted by different individuals, including the ozone generator manufacturer's technician and owner's staff. In all cases, the tests were either conducted or witnessed by one of the authors. This paper presents results focused on: 1) precision of UV meter readings, 2) accuracy of the wet-test meter or the UV meter, and 3) expected range in percent difference between UV meter readings and KI wet-chemistry test ozone concentration results for the particular type of UV meter and wet-test meter used in the tests.
