Provided herein are sondes having a pressure sensor that is separated from active sensing portions of the other sonde sensor or sensors by a longitudinal distance along the sonde. The pressure sensor may be positioned in the base portion of the sonde, with removable sensors connected thereto with a sensor plane at a distal end of the sensors that measures any number of parameters associated with the liquid in which the sonde is immersed. An orientation sensor positioned in the base portion determines an orientation angle of the sonde that, in combination with the depth determined at the pressure sensor location by the pressure sensor, provides the ability to determine the actual depth of the sensor plane, irrespective of orientation angle. Accordingly, improved depth measurement is achieved, without having to confine placement of the pressure sensor at the sensor plane.
