These amperometric sensors are ideal for use in drinking water simple free Chlorine design Measure free Chlorine without having to deal with messyand expensive reagents. Continuous pH correction compatible when used with anauxiliary pH Sensor . Integral Pt-100 resistance temperature device (RTD) allowsfor automatic temperature compensation.

2 Operates in samples up to 122 F (50 C) and 65 psig. Sensor measures free Chlorine consistent with EPAR egulation of maintenance and installation 1-in. male national pipe thread (MNPT) process connectionssuitable for mounting in a low flow cell installed in asidestream sample. Replacing the membrane and electrolyte solution is fast andeasy and requires no special tools or fixtures. Variopol (VP6) cable connection options, for quick cable-to- Sensor release, eliminates cable informationRosemount 499 ACL-01 Free Chlorine Sensors are available witheither an EMI protected integral cable or a Variopol (VP6)interconnecting cable (sold separately).

3 These sensors aregenerally mounted in a flow cell installed in a sidestreamsample. Three replacement membrane assemblies, three O-rings, and a 4 oz.
