SEN12512 Access Tube Sensors

The SEN12512 is an EasyAG probe with an SDI-12 interface and a 50-cm length. This probe provides water content profiles for cultivated soils of good tilth—commonly found in vegetable production areas. It is unsuitable for stony soils where the average stone size is greater than 10 mm; EnviroSMART should be used for those applications.
