The O3 sensor is widely used in water disinfection, food processing and purification, food storage and preservation, medical and health, and household disinfection and purification.
In ozone applications, a certain concentration of ozone is an important parameter to ensure disinfection, energy conservation and pollution prevention.
But as If the concentration of ozone in the environment is too high, it will cause harm to the human body. Therefore, it is very necessary to effectively monitor the concentration of ozone.
The transmitter uses electrochemical technology to measure O3 concentration, and the reaction is quick and sensitive, which can reliably detect ozone concentration.
degree. O3 sensor product uses 485 communication, standard ModBus-RTU communication protocol, communication address and baud rate can be set, the farthest passThe letter distance is 2000 meters. The equipment is 10-30V wide-voltage power supply, and the enclosure has a high degree of protection, which can adapt to various harsh conditions on site.
