Home » 7300w² Monitor
The 7300w² Monitor is the core product in the WaterWatch² range. The monitor is designed to interface with all of the sensors in the WaterWatch² range. The monitor specification provides all the connections required for 1 or 2 sensors, systems can be created by the use of expansion boxes to include multiple sensors. The maximum number of sensors will be limited by the practicalities of most sites. We anticipate 8 being a sensible maximum although many more can be accommodated.
The 7300w² contains an inbuilt trending display, customer configurable, that shows the last 24 hours data for any measurement point on an easy to navigate graph. This can also be downloaded for reporting purposes. An external USB port and data logging function allows users to log and retrieve all stored data for a site in a standard .csv format without the need for specialist SD cards or compatible hardware.
Combining sensors provides a very cost effective way of simultaneously monitoring parameters such as dissolved oxygen and suspended solids in an activated sludge plant, or pH and turbidity at a treatment works outfall where the sensors can be located close together.
