ZONEWU RS485 Ozone (O3) Transmitter



Key Applications & Use Cases
Industrial Ozone Emission Monitoring: Our industrial ozone detector, built with an Electrochemical Gas Sensor, is ideal for manufacturing workshop exhaust monitoring and ozone generator efficiency tracking. This RS485 ozone sensor delivers real-time O3 concentration readings across a 0-100ppm range, while simultaneously tracking temperature (-20℃~50℃) and humidity (15%~90% RH). The sensor’s lifespan of >2 years ensures long-term stability, and its RS485 ModBus RTU output integrates seamlessly with environmental monitoring platforms for compliance reporting.
Indoor Ozone Safety Detection: As a dedicated indoor ozone monitoring sensor, this device provides precise measurements for cleanroom air quality control and ozone disinfection residual detection. The compact design and 5-28VDC wide voltage supply support multi-point networking, and it operates reliably in -20~50℃ temperatures (anti-condensation), providing early alerts for excessive ozone levels to safeguard personnel health.
Environmental Ozone Early Warning: This ozone gas sensor is engineered for rapid deployment in urban air quality monitoring and chemical park perimeter surveillance. Its proprietary compensation algorithm maintains accuracy even in variable humidity environments, and the ModBus RTU protocol enables remote data transmission. With robust anti-interference performance and a stable RS485 output, it connects seamlessly to emergency alarm systems, making it a critical tool for toxic gas leakage early warning.
