Purpose:
The new PR2 soil profile moisture sensor can quickly, accurately, and reliably measure the soil profile moisture content. PR uses new sensing technology to accurately measure the absolute soil moisture content. Widely applicable to various types of soil. The combination of PR2 and HH2 reading meters is an economical and practical multi-point mobile measurement method. PR2 can be used in conjunction with DL6 data collectors to achieve continuous dynamic monitoring of soil moisture. For continuous dynamic monitoring of multiple points, the DL2e data collector can be used.

Two basic technical indicators:

Three characteristics:
Measure absolute soil moisture content
Achieve research level accuracy
Handheld reading meter, convenient for multi-point mobile measurement
Combined with DL6 data collector to achieve dynamic continuous measurement
Using measuring tubes for easy insertion and removal
The connection part adopts IP68 fully waterproof joint
Built in universal soil calibration curve

Installation and Connection:
Users can choose PR2/4, which can measure 4 levels up to 40cm deep, or PR2/6, which can measure 6 levels up to 100cm deep.
The installation of PR2 requires a pre drilled hole with a diameter of 27mm to facilitate installation and minimize disturbance to the soil.
The HH2 reading meter can quickly and conveniently read and store soil profile moisture content. Multiple data management points can be set up. Connect HH2 and PR2, insert the PR2 probe into the measuring tube to directly read the data. A reading meter can store a large amount of data.
Single point operation and convenience, data can be downloaded and imported into an EXCEL spreadsheet. Can store multiple types of soil types in multiple locations. Users who already have an early HH2 reading meter can upgrade it to be used in conjunction with PR2.
