Adjustment instrumentation

Swimming pool water contains pathogenic and non-pathogenic microorganisms, which pose a risk to human health, and therefore requires a balanced chemical treatment to minimize microbiological risk. The UNI 10637: 2016 standard provides for some specific requirements regarding the measurement and regulation of disinfection treatments for classes A, B and C (systems for collective use), while UNI EN 10713 indicates the requirements for class D (systems for private use). The disinfection treatment takes place through the dosage of substances, regulated on a regional basis.

pH measuring and regulating equipment (type A, B, C range 4.5-8.5pH; type D range 6.8-7.6pH) must have an output signal to drive the dosing systems and proportional regulation is preferred for type A pools.

The FIP M9.00 series monitors combined with the 200 series pH electrodes are the ideal solution to meet these needs. RedOx potential measurement equipment can be used in type D pools in order to monitor the evolution of organic pollution of tank water and to drive disinfectant dosing equipment (RedOx >650mV). The FIP M9.00 Series monitors combined with the ORP 200 Series sensors provide an optimal compromise between simplicity and reliability. For classes A, B and C it is necessary to adopt systems for reading free chlorine values (range Cl2 0.6-5mg/I). The CLF6 series sensors, which can be combined with pH measuring instruments in the event of significant changes, fully comply with this requirement. For the most modern plants that use chlorine dioxide for chlorination, even with in situ production systems, FIP also offers the CLD6 series range of amperometric sensors, dedicated to the direct measurement of this parameter.
