Discussion franche au sujet des analyseurs de chlore à « surveillance continue »

Some manufacturers of online chlorine analyzers are making bold claims that their sensors enable ‘continuous monitoring for real-time decision-making,’ which raises the question, ‘What do they mean by ‘continuous monitoring’?’ Hint: Their definition might not match your definition…or the definition. At Halogen Systems, we think about monitoring in terms of cycle times: How fast can the unit take, measure, and record a parameter data point? In the case of a wet-tap drinking water installation (retractable in-pipe deployment), the Halogen MP5 wet-tap chlorine analyzer is situated directly inside the water flow, utilizing its three bare electrodes to record a measurement. The analyzer then combines this reading with data from its onboard pH and temperature sensors. Finally, the MP5™ reports five parameters (free chlorine, pH, temperature, conductivity, and RapidORP™) via the display/controller unit and then takes another measurement. From measurement to reporting, the cycle takes approximately 50 seconds. If you’d rather think of cycle time in terms of Cycles Per Hour (CPH), the MP5™ runs at 72cph {(60/50)x60}.
