Note: The SEN12512 is only available in a limited supply and will be discontinued after the supply is exhausted.  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. For stony soils where the average stone size is greater than 10 mm, use the EnviroSCAN probe.
