Rosemount™ 499ACL Chlorine Sensor

The Rosemount 499ACL Chlorine Sensors are used for measuring free chlorine, total chlorine or monochloramine. The free chlorine sensor doesn't require sample pre-treatment or expensive reagents to maintain. The total chlorine sensor eliminates the need for pH correction with a standard reagent sampling system. And the monochloramine sensor doesn't not use reagents or sample pre-treatment for measurement. All three chlorine sensors have an easily replaceable membrane that does not require special tools. These amperometric sensors are ideal for use in drinking water applications. Measurement Range: 0 to 10 ppm (mg/L) as Cl2.
