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).

Augering and Extraction Kits – for optimal Access Tube installation

Pro?le Probes are used within access tubes inserted into augered holes in the soil – correct installation is vital for accurate measurement of soil moisture pro?les. The goal of installation is to produce optimal contact between the soil and the wall of the access tube. The augered holes should be straight, smooth sided and the correct diameter.
