We manufacture 20 presentations of packs, on a CPC quick disconnect. A basic pack is made of a soil temperature sensor + 3 pairs of Watermark sensors + air temperature sensor. The 6 Watermark sensors are mounted on pvc pipe, reduced to double diameter, to secure perfect contact with the soil. Each pair of Watermark sensor is cabled to the cpc with 3 sheltered cable , respectively measuring 6m, 6m et 14 m. This allows 3 repetitions in field, which is a statistical minimum necessary to adress cultived soils structure heterogeneity and also water distribution heterogeneity in different irrigation modes : submersion, fload irrigation, gravity irrigation, micro-irrigation, drip irrigation. Watermark sensors measure water tension in the soil beetween 0 and 239 cb (or KPa), in almost all situations of crop, weather, soil, irrigation equipement.
We also test and repair those packs in our plant. To give them a second life, at reduced cost.
