How can the concentration of chlorine dioxide in the water pipe be measured?
The concentration of ClO2 in the water can be measured manually using a hand-held photometer. This method has the advantage that measurements can be taken at different locations in the building, but the readings have to be recorded by hand. This is not the case with automatic measurement. A measuring cell with a sensor to measure the chlorine dioxide can be connected directly to the Oxiperm Pro and show the readings directly on the Oxiperm Pro display. No additional measurement amplifier is required. The manual and automatic devices are both described in the data booklet.
