What is a Ozone concentration meter?

The ozone concentration meter (English: Ozone concentration meter) is a device that measures the concentration of ozone contained in the atmosphere and liquids. It is necessary to control the concentration appropriately in order to obtain an appropriate ozone concentration according to the purpose of use, or to prevent accidents and effects on the human body and the environment due to the generation of ozone. There are UV absorption method, semiconductor thin film method, constant potential electrolysis method, detector tube method, etc. as the measurement method of the ozone concentration meter, and the number is huge and the introduction cost and maintenance cost are various. It is necessary to consider each purpose of use, work range, work environment, size, accessories, consumables, etc. when selecting.

Application of Ozone concentration meter

The ozone densitometer is a device used to properly control the ozone concentration when introducing an ozone generator or in an environment where ozone is likely to be generated. Ozone is a compound useful in various industries such as sewage, water treatment, medical industry, sterilization / deodorization of foods, and storage. On the other hand, high concentrations have an adverse effect on the human body and the environment, and the Japan Society for Occupational Health has set an allowable concentration of 0.1 ppm (0.2 mg / m3) as a work environment standard. Ozone is also generated where there are ultraviolet rays and electric discharges in the air. Therefore, ozone densitometers are used not only near ozone generators but also in places where ozone can be generated in the work environment.
