EWS-4E-EC Electrical Conductivity Water Quality Sensor

Category Tag
  • The EWS-4E-EC conductivity sensors operate with an alternating voltage applied between the measuring electrodes, which will generate 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. To compensate for measurement errors caused by polarization, the EWS-4E-EC has a reference electrode, making the measurement results more accurate.
  • The EWS-4E-EC sensor has a built-in five-point interpolation algorithm that allows the user to calculate TDS and salinity from conductivity.
  •  It is widely used in tap water, surface water, groundwater, domestic sewage, and other scenarios to provide customers with stable and reliable data.
  • It can be matched with our TRM series data transmitter and Ulik-Server Cloud Service to realize remote real-time monitoring of data and remote operation and maintenance of equipment.
