Sonde

Description of the term: Sonde

One type of instrument package, sometimes called sondes, are ideal for profiling and monitoring water conditions in industrial and wastewater effluents, lakes, rivers, wetlands, estuaries, coastal waters, and the open ocean. Torpedo-shaped in appearance, sondes may have multiple sensors that record a range of water quality data. If the sonde has ?on board? battery power, it can be left unattended for weeks at a time, with measurement parameters sampled at preprogramed intervals and data securely saved in the unit's internal memory.
