Watermark sensor measures on a range 0 – 239 cbars, no maintenance, frost resistant.
The Watermark sensor is a rustical tool, accessible, that doesn’t need maintenance. Simple to use, accurate, pertinent. “Simple to use” does not mean that taking irrigation monitoring decisions can be done without a strong and square technique.
Watermark sensors are glued/riveted, on a semi-tender PVC tube, that is re-moulded back in 2 diameters 25/22 mm
This is to insure a perfect contact with the soil, in the pre-hole made with the special spiral installing auger, designed with the same double diameter 25/22 mm.
