TW-100 Water Distribution Monitor
Overview
HORIBA’s TW-100 is a process water quality measurement system designed for drinking water and water distribution plants. The TW-100 monitors turbidity, color, free chlorine and pressure. This chemical free method reduces operating costs as it requires minimal maintenance and improves process control.
Features
This compact system is equipped with sensors to monitor four water quality parameters. Optional sensors can be added to monitor as many as seven water quality parameters. No reagents are required for the measurement.
The instrument is operated with a touch screen panel for easy operation and display of measured values.
The compact size allows for more installation location options and space for operation.
