DM502-O3 type monitor is an intrinsically safe gas detector developed by our company for environments containing ozone gas. The detector uses natural diffusion. The gas is detected by an electrochemical gas sensor, which has excellent sensitivity and excellent repeatability.
This O3 detector is ideal for health, environmental, industrial and residential monitoring. Useful for detection of ozone residue after disinfection.
American O3 SPEC detector 0-5ppm Low concentration ozone sensor application:
1. Air quality monitoring
3. Air purification control
Our DM502-O3 is easy to use and maintain, and meets the requirements of industrial field safety monitoring for high reliability of the equipment. The shell is made of high-strength engineering plastic. It has high strength and good hand feel.

Why is Ozone Dangerous?Ozone is a tiny molecule which is composed of three oxygen atoms. It is highly reactive which makes it an unstable and potentially toxic gas. Ground-level ozone is considered to be a major component of smog which plagues larger cities during the summertime and has been tied to a variety of potential health risks.
Health Effects of Ozone
The EPA has reported there is a variety of health effects associated with high levels of ozone. This may include decreased lung function, throat irritation, severe asthma symptoms, cough, chest pain, shortness of breath, irritation of lung tissue, and the higher sensitivity to respiratory infection. They went on to note that there were additional risk factors which can perpetuate the side effects of ozone such as undertaking activities which raise breathing rates (such as exercising indoors), certain pre-existing lung diseases, and greater duration of exposure.
Our air quality monitor is used for various occasions:
