The Aquaread AP-2000 Aquaprobe is a slim 42 mm multiparameter probe built for regular low-flow groundwater sampling and portable field work. It reads optical dissolved oxygen, conductivity, pH, ORP and temperature as standard and calculates total dissolved solids, resistivity, salinity and seawater specific gravity. Two auxiliary sockets, one ion-selective and one optical, let you add sensors such as ammonium, nitrate or turbidity later.

Choose the standard probe or the AP-2000-D with a depth sensor, then pick how to read it: probe only, with a BlueLink Bluetooth device, or with a handheld GPS Aquameter. Packages ship in a rugged carry case with a 3 m cable terminated at both ends and accessories. The cable connects through all-metal AquaConn connectors, and extension cables are offered in 3, 10, 20 and 30 m lengths.
