PR2 Profile Probe Delta T Devices

Overview

Soil moisture content profiles down to 1 m

Dual purpose – installed and portable

Uses access tubes for easy probe insertion and removal

SDI-12 interface option available

No other soil moisture probe system enables you to monitor your soil water profiles with such ease and flexibility. Install an access tube into the soil, insert the PR2 Profile Probe and press the HH2 [ Read ] button to display an instantaneous reading, or connect the PR2 to a data logger ( GP2 or DL6 ) and leave the system to record soil moisture changes over time.

The PR2 soil moisture probe is built around patented sensing technology which provides unprecedented performance in all soil types, with minimal influence from either salinity or temperature. The PR2/4 model measures soil moisture at 4 depths down to 40 cm – the PR2/6 measures at 6 depths down to 100 cm.

Both analogue and SDI-12 interfaces are available for the PR2. Click here for information on SDI-12 Profile Probes.

Highly reliable field-proven instrument

Soil moisture content – not just trends

Out of the box solution – supplied with calibrations for common soil types

Portable meter option for multi-site measurement

The PR2 Profile Probe is available in two sizes to measure to a depth of 40 cm or 100 cm.

The PR2/4 has sensing elements at 10/20/30/40 cm

The PR2/6 has sensing elements at 10/20/30/40/60 and 100 cm

HH2 Meter

The HH2 is a versatile readout unit that provides an easy and convenient way to display and store readings from Profile Probes. With the HH2 and PR2 combination, a probe can be moved from access tube to access tube, enabling large amounts of soil moisture data to be collected at multiple sites.

Data Logging

Profile Probes are available with analogue or SDI-12 outputs.

For the analogue version, order PR2/4 or PR2/6.

For the SDI-12 interface version, order PR2/4-SDI-12 or PR2/6-SDI-12.

Please note that analogue and SDI‐12 probes cannot be mixed on the same cable system

Loggers for analogue Profile Probes

Delta-T offers a choice of two data suitable data loggers. Both have dedicated PR2 Profile Probe input channels and connectors:

The DL6 Data Logger can log one PR2/6 or one PR2/4 Profile Probe

The GP2 Data Logger can log up to two PR2/6s or three PR2/4s

Loggers for SDI-12 Profile Probes

The PR2 SDI‐12 is ideally matched to the SDI‐12 enabled GP2 Data Logger. Many SDI-12 Profile Probes can be connected to a single GP2 ( actual number depends on cable length, power, and other considerations ).

Further details of the PR2 SDI-12 can be found here.
