ZE14-O3 electrochemical ozone module is a general-purpose, miniaturized module. The electrochemical principle is used to detect O3 in the air, which has good selectivity and stability. Built-in temperature sensor for temperature compensation; at the same time, it has digital output and analog voltage output, which is convenient to use. ZE14-O3 is a general-purpose gas module designed and manufactured by closely combining mature electrochemical detection technology with sophisticated circuit design.
