SPS-EC Conductivity Water Quality Sensor
The conductivity water quality sensor operates with an alternating voltage between the measuring electrodes, generating a corresponding current in the medium. The magnitude of the current is positively correlated with the conductivity of the medium, thus measuring the conductivity of the medium. The SPS-EC has a reference electrode to compensate for the measurement errors caused by polarization, making the measurement results more accurate.
The SPS-EC sensor has a built-in five-point interpolation algorithm that allows the user to calculate TDS and salinity from conductivity. The SPS-EC series conductivity sensor uses an RS485 communication interface and Modbus RTU protocol communication, which is widely used and easy to use. It is widely used in tap water, surface water, groundwater, domestic sewage, and other scenarios to provide customers with stable and reliable water quality monitoring data.
