RS485 Modbus Dissolved Oxygen Sensor is based on the fluorescence quenching method, which can quickly measure dissolved oxygen in water, it has a built-in temperature sensor and salinity compensation to make the measurement more accurate. It has a long service life due to its unmatched chemical and abrasion resistance. And the sensor will not be affected by flow rate and chemical substances, resists interference from complex environments, and can be used in various scenarios such as aquaculture and wastewater treatment with simple deployment.
