OWS-MW Series Multi Wavelength Water Quality Sensor

  • Based on UV-Visible Spectral Absorption Method, the sensor uses 4 LEDs to identify water sample characteristics and innovative algorithms for measurement.
  • It can measure organic matter and nitrate nitrogen in water with a turbidity compensation function, which can effectively improve the accuracy of actual water sample measurement.
  • Scope of application: monitoring of domestic sewage, industrial wastewater,  sewage treatment, water sources, watersheds, etc.
  • The sensor is equipped with an automatic brush, which keeps the cleanness of window for a long period (~ 6 months) even in very dirty conditions.
  • It can be equipped 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.
