    Description
    Product Description

    The DEC351 Digital Conductivity Sensor developed and produced by Daruifuno has a wider measurement range of 0~100m/cm. This benefits from the four-electrode measurement principle, which can reduce the influence of electrode polarization and electrolyte concentration polarization, and improve measurement accuracy and stability. The four-electrode conductivity electrode can measure high conductivity samples, avoiding the measurement error of traditional conductivity electrodes for high conductivity samples. The digital Conductivity Sensor can be used alone, the protection grade is IP68, and it can be continuously measured online and monitored in real time underwater. The shell of titanium alloy is more corrosion-resistant and can be used in seawater to measure the conductivity value. It is suitable for the measurement of conductivity values related to seawater aquaculture industry or seawater treatment. The sensor has a built-in RS485 interface, supports modbus communication protocol, and is convenient for networking. Calibration data is stored inside, which can be calibrated offline, plug and play.

    Application

    The conductivity ranges for some common water qualities are as follows:
    Pure water: 0.055~0.1μS/cm, drinking water: 50~800μS/cm, tap water 100~500μS/cm, river water 50~1500μS/cm, sea water 50~60mS/cm, the conductivity value of industrial water depends on the water quality situation to choose.
    This DEC351 quadrupole conductivity electrode can be used for conductivity monitoring in drinking water, surface water, seawater, sewage and other industries.
