Smart amperometric Total Free Chlorine Sensor: 9184sc
The low minimum detection limit and wide measurement range of the Hach 9184sc Amperometric Free Chlorine Sensor makes it ideal for efficient residual chlorine monitoring. Continuously measures hypochlorous acid (HOCl), Hypochlorite ions (ClOˉ), temperature, and pH.
Benefits
Low Minimum Detection Limit for Efficient Residual Chlorine Monitoring
The Hach 9184 sc sensor has a minimum detection limit of 5 ppb or 0.005 mg/L hypochlorous acid in the form of HOCl.
Acidification Unit
Used to maintain 2% accuracy when sample pH is greater than 7.5. Alternatively, it can be used intermittently or continuously for cleaning and is fully programmable.
Wide Measurement Range
The 9184sc sensor is particularly useful for drinking water distribution monitoring, chlorination applications, demineralizer systems, wastewater, or cooling water processes due to its 0 to 20 ppm measurement range.
Continuous Chlorine Measurement
Measurements are made continuously by the sensor and reported to the controller
Compatible with Hach's "Plug and Play" Digital Controllers
The 9184sc Analyzer is designed to be used with all Hach SC digital controllers. Set up is fast and easy, and the system is compatible with the full line of Hach digital sensors.
Offers a low minimum detection limit for efficient monitoring
