General Description

The DS4X offers Hydrolab's Superior Sensor Technology on a platform that will dramatically extend your DataSonde's deployment life!

Benefits

  • Ideal for "X-tended" deployments in environments where fouling and sediment are abundant
  • Further improved long-term value due to reduced frequency of sensor maintenance
  • Central cleaning system wipes away fouling on DO, pH, ISE's, Chlorophyll, and Turbidity
  • One central motor cleans the entire suite of sensors – minimizes power consumption!
  • Hydrolab's brush design features robust fibers that won't separate over time
