Model FX-CLF Reagentless Amperometric Free Chlorine Analyzer
The Foxcroft FX-CLF amperometric reagentless chlorine residual analyzer provides continuous online free chlorine residual measurement without moving parts or buffers in a variety of applications that have water with filtered drinking or swimming pool quality.
Low maintenance and power consumption make the FX-CLF ideal for chlorine monitoring in remote locations.
The standard 3-electrode sensor measures free chlorine as HOCL and may be used in filtered water between 4-9 pH. The electrolyte provides a reduced dependence on pH. Most installations do not need pH compensation.
Iron and manganese levels must not exceed National Secondary Drinking Water Standards to avoid disrupting sensor operation.
If your water leaves deposits like this, or if corrosion inhibitors are used, we suggest the FX-CLv2 bare electrode model, membrane covered chlorine sensors simply cannot work in this type of water without pretreatment.
The 4.3” full color glass LCD touch screen is rated for minimum 1 million touches and simplifies calibration and configuration. It displays residual in mg/L (PPM), high / low chlorine alarm indication and processor status.
The feature packed RoHs compliant electronics platform provides expansion capability that can grow with your needs.
No chemicals are added to the sample, it can be recycled back into the process line if regulations allow, to conserve water or for installations without a drain.
Designed to operate 24/7, it's also suitable for intermittent operation at well sites and booster stations that only operate several hours each day, or simply to conserve water. Tolerates zero chlorine up to 24 hours.
No zero point calibration
