Fast Response Electrochemical O3 Detection Transmitter Analog RS485 Modbus Ozone Gas Sensor

Working, counter, and reference electrodes maintain stable potential. Reduction at the working electrode generates current directly proportional to O3 concentration for accurate ppm-level detection.

Two selectable ranges cover trace-level indoor air quality and disinfection monitoring up to high-concentration industrial ozone process control within a single product series.

Fine 0.01ppm resolution on the low range captures subtle ozone fluctuations critical for monitoring in food processing, medical, and water treatment facilities.

Duct model features a dedicated anti-interference circuit design that withstands strong electromagnetic disturbances from frequency converters and industrial motors inside ventilation pipelines.

Direct duct insertion exposes the sensor to concentrated airflow, achieving sub-35-second response compared to 180 seconds for wall-mounted natural diffusion models in the same product line.

Consistent repeatability under 2% and drift under 7% per year enable reliable long-term ozone trend monitoring without frequent recalibration in fixed continuous monitoring deployments.

RS485 wall-mounted model supports an add-on temperature and humidity module, enabling 3-parameter monitoring of O3, temperature, and humidity in one housing without additional sensors.

Duct model offers an OLED display add-on for real-time ozone concentration readout on-site without connecting to external devices.

RS485 variant draws only 0.1W across a 10 to 30VDC wide-voltage range, supporting flexible power infrastructure from solar panels to industrial panel supplies without voltage regulation.

Each unit ships fully calibrated. No secondary on-site calibration is required, eliminating reference gas equipment needs and reducing setup time from installation to first reliable reading.
