CALIBRATION
The GERBIL probe is supplied factory calibrated for mixed soil types, and the user can subsequently calibrate it for other soil types.
PROBE INSTALLATION
The GERBIL series moisture probe has a diameter of 33.5 mm. To install it in the soil, it is necessary to first drill a hole in the ground with a standard 35 mm drill bit.
