A salt sensor, suitable for use in situ in saturated and partly saturated soils, has been designed and constructed from readily available materials. The behavior of the sensor, within limits, is independent of the geometry of the surrounding medium. Under hydraulic stress, the sensor is limited to a range from 0 to −0.65 bars. Failure below −0.65 bars appeared to be due to cavitation of solution within the sensor. The response time in free solution is short and the calibration of sensors remained stable over periods of weeks.
