The Hach 9184 sc Amperometric Chlorine Analyser is ideal for drinking water distribution monitoring, chlorination applications, demineraliser systems, wastewater, or cooling water processes due to its 0 to 20 ppm range. The minimum detection limit of 5 ppb (0.005 mg/L hypochlorous chlorine in the form of HOCl) lets the 9184 sc excel at near zero chlorine readings. The all-inclusive 9184 sc free chlorine system comes pre-assembled on a panel. Just mount the panel in the desired location, insert the sensors, and connect the controller to get started. The membrane system of the sensor means there are no reagents used for measurement. Maintenance is minimal and two years of typical maintenance items are included with the system.
