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

The 6920 V2 is essentially a battery powered, logging version of the 6820 V2

Two versions of the 6920 V2 are available:

1. 6920 V2-1

• one optical port
• conductivity/temperature port
• Rapid Pulse DO port
• pH/ORP port
• 3 ISE ports
  

2. 6920 V2-2

• 2 optical ports
• conductivity/temperature port
• pH port
• 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.

Additional parameters available include:

		Temperature
		Conductivity, Salinity, Specific Conductance
		Depth or Shallow Vented Level
		pH
		ORP
		TDS
		Open-channel Flow
		Nitrate-nitrogen, Ammonia/Ammonium-nitrogen, or Chloride

Deployment intervals can be extended by 3 times or more with NEW anti-fouling kits.
