Water quality sensors are a general term for various sensors that measure PH, ORP, residual chlorine, turbidity, suspended solids, COD, BOD, conductivity, salinity, and dissolved oxygen.

1.TSS Supended Solids Sensor

Our Total Suspended Solids sensors use fiber optic technology to provide superior repeatability and stability, and are less susceptible to ambient light. The automatic cleaning brush with the sensor can effectively eliminate air bubbles and reduce the influence of contamination on the measurement. It has a longer maintenance period and maintains excellent stability for long-term online use.

2. Chemical Oxygen Demand (COD) Sensor

DS500 series COD sensor is a new generation of environmental protection type COD sensor launched by our company, which is reagent free, pollution-free, and more economical and environmental protection: small size, more convenient installation, online continuous water quality monitoring. Automatic compensation for turbidity interference, with automatic cleaning device, and even long-term monitoring still has excellent stability.

3. Dissolved Oxygen Sensor

The fluorescent dissolved oxygen sensor is based on the quenching principle of the specific fluorescence of the specific substance in physics. Blue light from a light-emitting diode (LED) illuminates the fluorescent material on the inner surface of the fluorescent cap, and the fluorescent material on the inner surface is excited to emit red light by detecting the phase difference between red and blue light and the internal calibration value. The ratio is calculated to calculate the concentration of oxygen molecules, and the final value is automatically compensated by temperature and pressure.

4.pH Sensor

Desun Uniwll digital pH sensor adopts industrial online electrode and built-in temperature sensor, which can automatically compensate for temperature, which is suitable for online long- term monitoring environment. The sensor adopts RS485 output and supports Modbus, which can realize networking and system integration without a controller.

5.ORP Sensor

Online digital ORP sensor with composite electrode detection method, suitable for complex

situations and easy to maintain. The built-in temperature sensor automatically compensates for

temperature and reduces the influence of temperature on the test results, providing excellent results even under long-term online conditions.

6. Conductivity Sensor

The DSC480 digital conductivity sensor adopts a new generation of four-electrode technology with a wide measurement range and can automatically switch the range. Automatic temperature compensation for the changing temperature of the water body. With strong anti-interference ability, the electrode can adapt to a variety of harsh water environments, the electrode will not be polarized in long-term use, reducing maintenance costs.

7. Ammonia Nitrogen (NH3-N)Sensor

The Ammonia nitrogen sensor is an online device for detecting ammonia nitrogen (NH4+-N) levels in water and is suitable for use in various water bodies, including lakes, streams, groundwater, and wastewater. The sensor measures ammonia nitrogen values by the electrode method. The NH4+ electrode provides the main measurement, which measures ammonia

ions (NH4+) with automatic temperature and pH compensation and an environmentally friendly design.

8. Turbidity Sensor

Our turbidity sensors use fiber optic technology to provide superior repeatability and stability and are less susceptible to ambient light. The automatic cleaning brush with the sensor can effectively eliminate air bubbles and reduce the influence of contamination on the measurement. It has a longer maintenance period and maintains excellent stability for long-term online use.

9. Salinity Sensor

The digital salinity sensor adopts a new generation of four-electrode technology, with a wide measurement range and automatic range switching. Automatic temperature compensation for the changing temperature of the water body. With strong anti-interference ability, the electrode can adapt to a variety of harsh water environments, the electrode will not be polarized for a long time, reducing maintenance costs.
