The ion exchange resins remove cations and anions from water by exchanging H+ and OH-. Their uniform and compact mixed bed ensures reliable desalination and optimal utilization of the resin material, resulting to a conductivity of < 0.1 μS/cm (resistivity of 10 MΩ × cm).
The Arium® series also includes conductivity meters for checking the quality of the product water. These convenient options are available in a choice of LED-controlled display or digitally-controlled display. The LED-controlled conductivity meter enables the user to monitor the conductivity of the product water with a red (> 20 μS/cm) or green
(< 20 μS/cm) LED light. The digitally controlled conductivity meter lets the user monitor the conductivity by individually defined setpoint limits (0.1–200 μS/cm). The conductivity measurement range is between 0.056 and 200 μS/cm.
