| YSI 6920 
The YSI 6920 V2 sonde is an economical logging system, ideal for long-term in situ monitoring and profiling. Two versions are available:
- 6920 V2-1 has one optical port, conductivity/temperature port, Rapid Pulse DO port, pH/ORP port, and 3 ISE ports;
- 6920 V2-2 has 2 optical ports, conductivity/temperature port, pH port, and one ISE port. A pressure sensor is an option on both versions. Available optical sensors include ROX optical dissolved oxygen, blue-green algae, chlorophyll, turbidity, or rhodamine. The 6920 V2 will log all parameters at programmable intervals and store up to 150,000 data sets. Extend deployment intervals by 3 times or more with NEW anti-fouling kits. Additional parameters include: - Salinity
- Specific Conductance
- Depth or Shallow Vented Level
- TDS
- Open-channel Flow
- Nitrate-nitrogen, Ammonia/Ammonium-nitrogen, or Chloride
You can rely on the accuracy and reliability of YSI's sensor technology - the performance of select sensors on the 6920 V2 has been ETV Verified.*
