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
