Water Quality Sensors


Turbidity Self Cleaning

Hydrolab Series 5 sondes use a self-cleaning turbidity sensor that measures from 0 to 3000 NTU and includes a user-programmable cleaning system to remove fouling or debris that could potentially affect readings.

  • User-programmable, self-cleaning system can perform up to 10 cleaning cycles before each reading, and the sensor’s fixed parking position ensures consistent data collection after each cycle.
  • Superior corrosion resistance in saline environments with a plastic sensor housing and titanium wiper shaft, rated to depths of 200m.
  • 0-3000 NTU range allows turbidity tracking with exceptional linearity, even during rain storms or other events that cause abnormally high readings.
  • Utilizes a small aperture technique to reduce false readings from particulates and other debris.
  • Designed to be compliant with the ISO 7027 Turbidity Measurement Standard.
