Conductivity in Pool & Spa

Conductivity in Pool & Spa

Maintaining proper levels of salt in pool and spa environments is critical to ensure the appropriate balance of water chemistry. For saltwater chlorinator equipped pools, conductivity measures the salinity to enable efficient disinfection. In freshwater pools and spas, total dissolved solids (TDS) is determined by conductivity to keep alkalinity, corrosion, and scaling under control. AlpHa has sensor solutions uniquely tailored to these applications, including field electrodes, continuous (process) monitoring sensors, and multiparameter sensors with conductivity.
