Amperometric Total Chlorine Analyzer FX-CL-T

Simplified online measurements



What It Does For You

The Foxcroft FX-CL-T analyzer gives you a hassle free, lower cost way to measure total chlorine residual.

Its continuous measurement and output is best suited for monitoring and process control in drinking water, wastewater effluent, sea water and pool water.

Stability, no need for pH sensor calibration and no chemicals to replace makes the analyzer a good choice for unmanned booster stations or anywhere that hands off operation is needed.

Total Chlorine Probe

The membrane covered three electrodes in this amperometric sensor measures the sum of free and combined chlorine (chloramines) and organically bound chlorine.

It cannot distinguish between different species of chloramine.

3-electrode circuitry eliminates zero point drifting for more stable readings.

No zero point calibration is necessary.

Easy to Operate and Maintain

With no moving parts or potassium iodide to replace it has lower maintenance and ownership cost compared to reagent based systems.

Simplicity of the system allows you to avoid costly service contracts.

Reduced pH Effects

The effect of pH on residual measurements is less than standard sensors due to the acidified electrolyte in the membrane cap. The sensor operates within a range of 4-9pH.

Compensation via pH sensor and algorithm for total chlorine is not feasible due to the complexity and speed of reactions between chlorine, ammonia, nitrogen forms, pH, temperature and ionic strength among other factors.


Standard Features

The analyzer comes pre-assembled with everything needed on a 12" x 24" PVC panel.

User friendly interface and glass touch screen make it simple to commission, calibrate and use for typical operators.

Choice of sensor operating ranges: 0.05 - 0.5, -2, -5, -10 and  -20mg/l (ppm).

For convenience the 4-20mA output is automatically scaled when the operating range is set.

(2) 1A SPDT relays for high and low chlorine

All inputs and outputs are protected against over voltage

Options include temperature measurement and output, no flow alarm and data logging.

Consider Carefully for Wastewater

The process solution must not contain oils and greases or detergents and cleaning agents.

Use in clear tertiary treatment effluent is possible.

For most wastewater applications or potable water with elevated levels of iron, manganese, suspended solids or hydrogen sulfide we recommend the bare electrode model FX-CLv2 which is more tolerant of poor water quality.
