The AquaPlus probe is a combined optical dissolved oxygen, electrical conductivity and temperature sensor. Thanks to the built in conductivity sensor, the AquaPlus is able to calculate and automatically compensate DO readings for changes in water salinity. It’s compact, robust and highly accurate. It also requires very little maintenance to keep it that way. The slim probe is used with its very own GPS DO meter, meaning the location of every datapoint you measure is also recorded.
