Partech 7300w² Monitor

The 7300w² Monitor is a water monitoring system and the core product in the WaterWatch² range. The monitor is designed to interface with all of the sensors in the WaterWatch² range.

The 7300w² is now SPAN (Suruhanjaya Perkhidmatan Air Negara) certified! 

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.
