HydraProbe

The Steven’s HydraProbe is a single level soil moisture sensor which may

be used as an insertion probe or buried in the soil at a fixed depth. The
sensor measures soil moisture, soil temperature and EC.

The HydraProbe is a robust, accurate single level soil sensor, which measures soil moisture, soil temperature and soil conductivity. Using these three readings it is then able to calculate the EC of the water held in the soil pores – the salt level the plant sees.

The HydraProbe can be used as a portable probe for turf applications or buried

below the surface for monitoring at a specific depth. Multiple sensors may be
connected to the same logger.


The HydraProbes may be installed in an over-sized hole drilled into the soil with a 40mm auger. The probe pins are pushed into the soil at the bottom of the hole
using a push rod and the hole backfilled with a mix of sand & bentonite. For
shallower sites, a hole can be opened up with a spade or post hole digger and the probe pins pushed into the undisturbed soil on the side of the hole. The hole can then be backfilled.

The HydraProbe sensor may be connected to any data logger which supports the SDI-12 serial interface specification.
