EDK 7100 online ozone gas analyzer
Overview
Online EDK 7100 ozone gas analyzer of ETG Italy, based on Beer-Lambert Law for ultraviolet light sources. Ultraviolet light at the wavelength of 254nm is absorbed by O3 when passing through the sample chamber of O3 gas. The absorption value and the concentration of O3 follows Beer-Lambert Law. By measuring the change value of ultraviolet light signal before and after absorption and comparing with the reference light source, the concentration value of O3 was analyzed.
