DataSonde 5 (DS5)



 

The newest generation Series 5

multiparameter probes are designed

specially for measurement of water

quality in surface waters, ground water

and wastewater areas.

 

The DataSonde 5 (DS5) allows for 

simultaneous measurement of up to 

15 water quality parameters.

 

7 additional sensor inputs enable you

to customise the probe for specific

applications.

 

The probe is suitable for point-to-point  measurement and continuous measurement with data storage.

 

 

Features

 

  • Extremely low maintenance requirement due to the use of newest sensor technology (LDO) for oxygen measurement.
  • Unique sensor technology to determine chlorophyll a and cyanobacteria.
  • Versatile, since combined sensor technology enables up to 15 parameters to be detected at a time.
  • System integration possible through a variety of signal outputs: RS-232, RS-485, SDI-12.
  • Two year guarantee for the probes, including sensors.
  • Autonomous operation through internal datalogger (approx. 120,000 measurements).
