A free software tool is available for use with Global Water’s family of data loggers
that allows the WQ-FDO sensor’s two 4-20mA outputs to be monitored, along
with optional conductivity and barometric pressure sensors, to determine the
oxygen concentration and saturation levels. If the optional sensors are not used,
provision is made for the hand entry of barometric pressure (or altitude) and
conductivity (or salinity) into the calculation. The partial pressure, concentration,
saturation, temperature, conductivity, salinity, and barometric pressure can all be
displayed in real time, or can be downloaded for use in a spreadsheet program.
The standard sensor comes with one meter of cable between the sensor and
interface module, and 25 feet of marine grade cable for connecting to recording
devices. Additional cable can extend the length up to 1000 feet. A protective
armor shield is also available in either plastic or stainless steel.
