The EXO Sonde from Xylem is a multiparameter water quality meter which can measure and log data. The EXO1 in the Van Walt rental stock will be configured to measure and log the following parameters simultaneously: pH, EC, Temperature, Redox, Dissolved Oxygen and Turbidity. When connected to the Storm 3 telemetry unit, additionally, it will also report water level.
The EXO Sondes are very special and the result of a US$ 24 million investment programme. The idea was to create the ultimate water quality measuring device and no shortcuts were taken. The EXO's have a host of features, viewable on the specification sheets but a few are worth focusing on:
The robust, multiparameter, 4-port EXO offers a wide range of capabilities for groundwater monitoring of:
The EXO is smart, cost-effective and adaptable for the future. Its high-impact body is built to record water quality to depths of 250 meters. The data is stored on-board the instrument for downloading to a laptop on completion of the monitoring sequence.
The EXO logger is also available with telemetry.
