During installation, the conductivity of the tap water inlet was 650 µS as measured with an American Marine Pinpoint conductivity meter set to the low range (0-2000). The product water exiting the membrane and fed into the DI canister was 15 microsiemens, corresponding to 97 to 98 percent removal of inorganic salts. The conductivity of the water produced leaving the deionization…
