When measuring chlorine there are many options for online systems. Chemtrac’s Reagentless Chlorine Analyzer is highly customizable depending on the needs of your facility, keeping your measurements accurate and helping to ensure chlorine-free outputs.

Chemtrac sensors are amperometric, meaning they rely on electroanalysis to read the chlorine content of discharge. All available options through this system offer a reduced need for maintenance compared to any system that relies on reagent-based analysis, plus there are many configurations to further lighten the load associated with maintaining chlorine measurement systems.

Chlorine Analyzer Systems from Chemtrac

Type of Sensor	+	–
*Two electrode open systems (when the electrode comes into contact with the sample)	– Fast responding – Reagentless	– pH dependant – Zero drift – Susceptible to fouling – Electrode gets used up so limited life
Three electrode open systems (when the sample comes into contact with the electrode)	– No zero drift – Fast responding – Reagentless	– pH dependant – Susceptible to fouling
*Two electrode membrane systems (not pH corrected internally)	– No zero drift – No electrode fouling -Reagentless	– pH dependant – Electrode has limited life – Susceptible to fouling
*Two electrode membrane systems (pH buffered internally)	– No zero drift – No electrode fouling – Largely pH independent – Reagentless	– Electrode has limited life – Susceptible to fouling
Three electrode membrane systems (pH buffered internally)	– No zero drift – No electrode fouling – Largely pH independent – No electrode loss so extraordinary long life – Reagentless	– Susceptible to fouling (Unless supplied with an automatic cleaning system)

These systems are known to be particularly useful when reporting chlorine levels to EPA standards (334.0) as the Chemtrac HydroACT automatically logs events.
