Water quality analysis device

Known as the WaterDOG, this compact device can measure and transmit multiple water quality parameters simultaneously over a continuous period

Water purification processes require validation by testing samples both before and after the purification process to ensure that the water meets specific standards for quality.

Typical testing parameters include water temperature, pH, conductivity, and turbidity, as measured by sensors. But, commonly employed water testing sensors are difficult to use when taking continuous measurements.

Most sensors must be set up individually, and measure only a single parameter at a time. Manifolds that allow deployment of multiple sensors simultaneously require advance set-up and deployment and have limited applicability for fieldwork because they are not designed for all-inclusive flow characteristics. Furthermore, existing systems are not designed to integrate multiple types of data, nor are they designed for general-purpose use.

To fill this gap in current offerings, the Army has developed a water sensor flow cell which accommodates several sensors in direct contact with the water under test within a manifold. A stream of water flows continuously through the manifold and sensors continuously transmit data values. The probes measure pH, T°, turbidity, conductivity, oxidation-reduction potential, total dissolved solids, dissolved oxygen, chlorine, arsenic, cyanide algae and a host of other variables. A pump may be included to flow standing water.
