DataSonde 5X (DS5X)



 

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 5X (DS5X) 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 central brush motor cleans all sensors 

before each measurement and prevents

the buildup of biofilms.

 

The probe is ideal for long-term use, with minimal maintenance required.

 

 

 

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).
