Chlorine and PH
You'll determine Chlorine with handheld devices photometrically, or continually with an internet measuring and control instrument.
We recommend our ready-to-use systems for online Chlorine dimension: at constant pH values, our Krypton K, as well as fluctuating pH values, our Krypton K Multi with integrated pH dimension and pH-compensation of the Chlorine dimension.
Our systems have all components necessary for the measurement and a number of safety precautions. Just click here for more info.
For on the web dimension you need an evaluation means for calibration. Our photometer Radon FM is essentially designed for such purposes.
Exactly why is an evaluation strategy required? Because all Chlorine particles that get to the electrode surface contribute to the measuring sign. This results in a flow impact of measurement. Without flow, the signal falls to zero. Unique flow-cells must optimise water flow, sufficient reason for these a reduction of movement from 50l/h to 40l/h lowers a measured value of 0.30 mg/l to 0.28 mg/l. To take into account the influence of flow along with other measuring circumstances, you calibrate the measurement after set up. And since Chlorine detectors tend to be putting on parts comparable to pH detectors, the sign production can reduce over time, making recalibration essential.
