ISA ion concentration analyzer

ISAIon concentration analyzer
The Qingmiao online ion analyzer uses ion selective electrode measurement method to simultaneously detect fluoride ions, nitrate ions PH、 Water hardness (Ca2+, Mg2+ions), K+, Na+ions.
Application areas; Mineral water, tap water, purified water, drinking water, surface water, industrial production water, and sewage.
