Online Water Quality Monitor
HORIBA's TW-150 is a process water quality measurement system designed for drinking water and water distribution plants. TW-150 monitors turbidity,color, free residual chlorine, water pressure and pH without any reagent for measurement.
This chemical free method reduces operating costs as it requires minimal maintenance and improves process control.
Measurement method for turbidity is direct NTU value by 90 degree light scattering method and comply with ISO 7027.
Touch panel operation
The instrument is operated with a touch screen panel for easy operation and display of measured values.
●Operation panel specifications
●The adoption of transparent measuring cell enables sample conditions to be easily confirmed.
●The use of thumbscrews makes maintenance easier as special tools are not required.
