Partech 7300w² Monitor

Part of the WaterWatch² range, the 7300w² Monitor allows for monitoring of a range of values and can comfortably accommodate up to eight sensors, with additional sensors a possibility depending on site capacity.


Key features include:

  • Easy to read LCD display, visible even in direct sunlight
  • Large touch buttons with feedback for use with gloves
  • Intuitive menu structure to allow for minimal training and setup
  • Inbuilt customer configurable trending display, allowing easy access to the last 24 hours of data
  • 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
  • User-friendly LCD display and
  • Automatic registration and set up of sensors when connected


Measurement options

Using the 7300w² Monitor, we can offer the following measurements:


Wastewater temperature monitoring

When monitoring final effluent, discharge consents are sometimes waived when the temperature drops to 4ºC. Accurate temperature monitoring using the correct equipment can help avoid regulation issues.


The WaterTechw² TMP Sensor can be combined with the WaterWatch 7300w² Monitor to provide highly accurate temperature measurement between -10°C and +80°C with a measurement accuracy of +/- 0.3°C.



Turbidity is a measurement of how transparent a liquid is and is considered a good measurement of the quality of water.


It’s also a key indicator of how a sewage treatment works is performing as increased turbidity indicates sludge blanket breakthrough, which can be caused by excessive levels of flow or a failure in the treatment process.


We can monitoring turbidity using Partech’s TurbiTechw² LS Sensor, which can be combined with the WaterWatch 7300w² Monitor to provide a comprehensive monitoring solution for the levels of turbidity in final effluent.


pH monitoring

pH levels are measured on a scale from 1-14, with values below 7 indicating acidity and values above 7 indicating alkalinity. pH is a critical component of wastewater makeup as its value has a direct impact on how it is treated.


Even small changes in pH levels can pose serious environmental issues, as they can impact the health of biological systems and chemical dosing required so it’s essential that they are tested using accurate and robust equipment.


The WaterTechw² pH8000 pH Sensor uses a flat surfaced electrode to provide highly accurate pH measurements when combined with the WaterWatch 7300w² Monitor.


Cloud-logged data

Data collected from the WaterWatch 7300w² Monitor and associated sensors can be combined with our specialist Cloud-based data monitoring system, allowing you to see all the results in one place – with 24/7 access from any location.


Data monitoring allows you to gather crucial flow meter data and ensure you are satisfying regulatory compliance for your water authority, as well as environment agencies in both England and Scotland.
