TW-150

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.

Division: Water Pollution
Fabricant: HORIBA Advanced Techno Co., Ltd.

Turbidity Method

Measurement method for turbidity is direct NTU value by 90 degree light scattering method and comply with ISO 7027.
Measurement of turbidity and color is performed with a single cell (patent pending).

Standard

5 parameters
Turbidity, Color, Free residual chlorine,
Water pressure, pH

Option

7 parameters
Turbidity, Color, Free residual chlorine,
Water pressure, pH, Conductivity,
Water temperature

Touch panel operation

The instrument is operated with a touch screen panel for easy operation and display of measured values.

●Operation panel specifications
320 x 240 dots
Black and white graphic LCD with backlight

 

User-friendly function

●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.
