Hi in cartridge replacement when the resistivity of the water drops below the desired level replace all cartridges with new one so what is the resistivity level who determent that thanks
Answer
What matters is your own procedures as to what purity you need. Generally you set a specification and an action limit. Some application require 18 megohm so if it is lower you would change the filters. Other may need only 10 megohm or even 2 depending on the water specifications selected. Most laboratory application require type I water.
This high capacity four housing lab water system is designed to provide up to 3 l.p.m. of ultrapure water exceeding ASTM and CAP Type I, II or III specifications.
