The ion exchange column of the HUAYUANFILTERGLJ-2Y-6P conductivity meter adopts a stainless steel shell and a built-in plexiglass liner. An observation window is installed on the housing. Both ends are quick connectors with check valves, which are easy to disassemble and assemble to ensure that there is no water leakage when the ion exchange column is replaced.

The ion exchange column GLJ-2Y-6P has a glass visible window. When the acid value of the anti-fuel oil increases, the phosphoric acid and the metal powder in the diatomaceous earth chemically react to form metal soap or metal salt to harm the servo valve. It will often block the Filter Element, and grind the valve core after entering the servo valve, which may increase internal leakage, and in severe cases, the servo valve will be scrapped. When metal salt is found in the system, the servo valve will be damaged in batches, the filtration cannot be improved, and the oil change is a necessary way.
