Pr2 Profile Probe Analogue Version - China

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.
