The HS2 is the handheld display for the new Hydrosense II soil-water sensor. When paired with either the CS658 or CS659 portable soil-water probes, it replaces the previous Hydrosense soil-water system. It features a new handheld display and a new probe design. The HS2 handheld has been designed to be compact and portable, with the layout of the buttons allowing for operation with one hand.Read More

The HS2 is the display used in the Hydrosense II System.
The water content sensor is ordered as an option, and may also be purchased separately. Either the CS658 or CS659 can be used with the HS2. The CS658 has 20-cm rods, and the CS659 has 12-cm rods.
Note: The CS658 and CS659 cannot share rods (i.e., 12-cm rods cannot be used with the CS658, and 20-cm rods cannot be used with the CS659).

No. The displays and sensors are not interchangeable between the HydroSense and HydroSense II.
No. These products are retired.
No. The HS2 uses Bluetooth communication.
When Deficit Mode is used, a value greater than 100% RWC indicates that the water content is above the wet reference. For more information, see the "Water Deficit Data" subsection in the "Operation" section of the HS2 Instruction Manual.
As stated in the "Connecting via Bluetooth" subsection in the "Data Storage and Retrieval" section of the HS2 Instruction Manual: “The first time the HydroSense II unit is used with a new computer, the computer and HydroSense II must be ‘paired’ before a connection can be made. The pairing code is ‘1234.’” For more information, see the "Connect to a Device" subsection of the "Quickstart" section of the HydroSense II Support Software User Guide.
Yes. See the "Connecting via Bluetooth" subsection in the "Data Storage and Retrieval" section of the HS2 Instruction Manual.
A VWC reading of (---) indicates either that the water content of the soil is greater than 50% or that the EC (electrical conductivity) of the soil is out of range. For more information, see Sections 6.3, 18.104.22.168, and 22.214.171.124 of the HS2 Instruction Manual.
