The WaterTechw² FCL sensor is ideal for monitoring free chlorine in drinking water, seawater, process water, swimming pool, wastewater applications.
The enhanced amperometric sensor is enhanced with a third, reference electrode which eliminates zero drift and the unique design means that pH compensation is not usually required. This combination of features removes the needs for buffers and reagents and keeps operator maintenance to a minimum and delivers exceptionally low cost of ownership.
The sensor integrates with the WaterWatch² product range and the 7300w² Monitor allowing the sensor to be combined with pH, Redox, Turbidity and other measurements, keeping installation costs and space requirements down. The 7300w² monitor is rightly recognised as one of the easiest to use monitors on the market avoiding any need for specialist training.
