UK-based Aquaread has launched the Aquaplus, which is a portable optical dissolved oxygen solution. Its black meter has an intuitive user interface that makes it suitable for use in the field. The tough meter features an air pressure sensor and a GPS receiver.
The device is 2.4cm in diameter and its aluminum encasing protects its single electrode, which is fitted with an Optical DO, conductivity and temperature sensors. The conductivity sensor helps automated compensation for salinity. This feature leads to exact saturation measurements that are fully compensated and needing no other user input.
It detects Optical DO saturation, Optical DO mg/L, Conductivity, Total dissolved solids, Resistivity, Salinity, Seawater specific gravity, Temperature, Air pressure, Height above MSL, Time, Date, Latitude and Longitude. It is suitable for applications such as fish farming and brewing. It offers surface, ground and waste water monitoring.
