GroPoint - Model Classic - Original Analog Soil Moisture Sensor
GroPoint™ Classic is our original analog soil moisture sensor, with a rugged design that has been proven over decades of use. The sensing element is manufactured from a solid 7mm (0.28″) stainless steel rod, and all electronics are sealed in water-proof epoxy. The 4-20mA output integrates easily with common irrigation control and management systems, and it’s also available with 0-5mA output. The standard 5m cable can be extended to up to 150m (500′) and terminates in a rugged IP66/68 environmental connector or bare wires.

The soil moisture sensor features a larger area of influence than our other sensors-about 10cm (4″) surrounding the sensing element. It can be calibrated specifically for sandy soils, high salinity and clay soils or a broad range of soils. Please specify when ordering.
The GroPoint Classic responds immediately and accurately to changes in soil moisture. It’s extremely rugged, easy to install and requires virtually no maintenance, providing years of reliable service.
- Fully potted electronics for excellent durability.
- Stainless steel sensing element provides years of maintenance free, reliable sensing.
- 4-20 mA interface provide easy and simple integration into common irrigation management and control systems. Also available with 0-5mA output.

* 8% to 42% VMC, in controlled laboratory conditions; factory calibrated for most agricultural soils. In field applications, accuracy may slightly decrease due to the inevitable heterogeneity of soil texture, soil compaction, moisture and fluctuation in soil temperature. The accuracy may also decrease in difficult soil conditions (higher clay and salinity content). In normal conditions, GroPoint sensors will maintain their accuracy from permanent wilting through field capacity in sandy loam through clay soils with less than 60% clay particles. Under moderately saline conditions. GroPoint sensors will maintain their accuracy up to 6 ds/m.
