Digital RS485 Four-electrode Conductivity Salinity Sensor for
sewage treatment
Daruifuno digital flat-head four-electrode conductivity sensor
DEC360 can measure both conductivity and salinity. The conductivity
measurement range is 0~200mS/cm, and the salinity measurement range
is 0~100ppt(‰).
The material is made of titanium alloy shell, which is resistant to
high pollution and seawater. It is widely used in high-precision
conductivity measurement equipment in industrial water treatment,
sewage monitoring, drinking water and chemical process control.
The flat head structure design is easy to install and flush, not
easy to scale, suitable for installation in circulation pools,
pipelines or immersion scenes, built-in digital communication (such
as RS485 MODBUS) has stronger anti-interference ability than
traditional analog 4-20 mA and supports long-distance
communication.

Features＆ Advantages - Protection grade IP68, can work continuously under water for a long
time
- Strong anti-pollution ability: Compared with the traditional
two-electrode conductivity, the four-electrode conductivity can
effectively eliminate the polarization effect, is not easily
affected by scaling, oil, and electrolysis products, and is
suitable for high-pollution or high-conductivity environments.
- Wide range: It can detect both conductivity and salinity.
- It can accurately measure conductivity from 1 μS/cm to 200 mS/cm
and salinity from 0 to 100ppt (‰)
- High linearity and stability: The four-electrode design avoids the
influence of electrode polarization and contact resistance, and the
measurement results are more stable and reliable, and the response
is faster.
- Digital output anti-interference: Digital communication (such as
RS485 MODBUS) has strong anti-interference ability and supports
long-distance communication
- Flat head design is easy to clean and maintain: The flat head is
not easy to accumulate impurities, reducing the frequency of manual
cleaning, and is suitable for automated systems.Very resistant to
pollution
- Temperature compensation function: Built-in temperature sensor,
automatic conductivity temperature compensation, improve
measurement accuracy.
- Protection grade IP68, can work continuously under water for a long
time
- Stable measurement and higher accuracy
- Strong and durable structure, longer service life
- Made of titanium alloy, it is lightweight, high-strength, super
corrosion-resistant, and has excellent biocompatibility, making it
suitable for harsh environments (such as seawater, acid and alkali)
DEC360 Conductivity&salinity sensors are mainly used in the
following Aplication:
- Industrial process water (such as desalination, boiler feed water,
chemical circulating water)
- Municipal sewage/industrial wastewater treatment
- Drinking water and mineral water quality monitoring
- Agricultural irrigation water conductivity monitoring
- Seawater, brackish water treatment and monitoring
