Compact Data Sonde for Unattended Monitoring

 

The YSI 6920 V2 sonde is an economical water quality logging system, ideal for long-term in situ monitoring and profiling.

Real-time turbidity monitoring, dissolved oxygen monitoring, algae monitoring, and more.

 

The sonde comes in two versions:

  • 6920 V2-1 has 1 optical port, 1 conductivity/temperature port, 1 Rapid Pulse Dissolved Oxygen port, 1 pH/ORP port, and 3 ISE ports
  • 6920 V2-2 has 2 optical ports, 1 conductivity/temperature port, 1 pH port, and 1 ISE port

Available optical sensors:

  • ROX optical dissolved oxygen
  • Blue-green algae
  • Chlorophyll
  • Turbidity
  • Rhodamine

A pressure sensor is an option on both versions.

Additional parameters include:

  • Salinity
  • Specific Conductance
  • Depth or Shallow Vented Level
  • TDS
  • Open-channel Flow
  • Nitrate-nitrogen, Ammonia/Ammonium-nitrogen, or Chloride (ISEs)

Extend deployment intervals by 3 times or more with NEW Anti-Fouling Kits.

This product features:

  • Field-replaceable sensors
  • Choice between one or two optical sensor ports
  • Self-cleaning optical sensors and anti-fouling components for extended deployment
  • RS-232 and SDI-12 communications
  • Battery power for long-term deployments

Two versions are available:

The 6920 V2-2 with and the 6920 V2-1 with
  • 2 optical ports
  • Conductivity/temperature port
  • pH or pH/ORP port
  • ISE port
     
  • 1 optical port
  • Conductivity/temperature port
  • Rapid Pulse DO port
  • pH or pH/ORP port
  • 3 ISE ports
