The Aquaread AquaSonde series takes the sensors from the Aquaprobe range and adds internal memory and battery power, so a sonde can be left in a well, river, lake or estuary to log unattended. Each model reads optical dissolved oxygen, conductivity, pH, ORP, temperature and depth, with calculated salinity, total dissolved solids, resistivity and seawater specific gravity. Depth and dissolved oxygen readings use an internal barometric sensor, and a vented cable is recommended for deployments longer than a day.

Choose the model by size and sensor capacity: the AS-2000 is a 42 mm sonde with one optical and one ion-selective socket, the AS-5000 and AS-6000 carry four unrestricted auxiliary sockets (the AS-6000 adds a removable self-cleaning system), and the AS-7000 carries six. Setup, live viewing, calibration and data retrieval run through the free SondeLink PC application over USB, and a vented desiccant hub allows access while the sonde is submerged. Batteries are not supplied.
