RS485 MODBUS Dissolved Oxygen Sensor, Fluorescence DO Meter, Water Quality Monit

Product Description

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 to make the measurement more accurate.It has a longservice 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, andcan be used in various scenarios such as aquaculture and wastewater treatment with simple deployment.

Feature

🌱Measuring ranges:0~20mg/L or 0-200% saturation

🌱Temperature compensation:Makes the measurement more accurate

🌱No electrolytestorage,easy maintenance

🌱Fluorescence method principle

🌱Nooxygen consumption

🌱Anti-interference:No interference from chemicals such as sulfides.

Description

This RS485 Dissolved Oxygen Sensor is used to determine changes in dissolved oxygen levels, one of the primary indicators of aquatic environment quality. Based on the fluorescence quenching method so it can eliminate the process-related drift and no polarization time which can fasten the response time, enabling us to measure dissolved oxygen faster and more accurately.

The fluorescence method for measuring dissolved oxygen is based on the principle of fluorescence quenching. Blue light is used to excite the fluorescent material, which emits red light. The concentration of oxygen molecules affects the time and intensity of the emitted red light due to the quenching effect. By measuring the phase difference between the excitation red light and the reference light and comparing it with an internal calibration value, the concentration of oxygen molecules can be calculated.

It comeswith RS485 serial communications protocol and can be easily connected and integrated with other devices.It's compatible withSenseCAP S2100 - LoRaWAN® Data Logger - Seeed Studio to connect with the LoRaWAN® network, enjoying the benefits of low-power and long-range communication.

ThisRS485 Modbus Dissolved Oxygen Sensorcanalso connect to theSenseCAP Sensor Hub 4G Data Loggerto send data to the Cloud via 4G/3G/2G (SenseCAP server or client private server)
