Abstract
Abstract There are disclosed an ion selective electrode comprising a polyvinyl chloride series resin plate having a through hole; conductive member disposed along the through hole; ion sensitive membrane of a polyvinyl chloride series resin membrane; and a lead wire connected to the conductive member, and the flow type ion sensor comprises a plurality of the ion selective electrodes mutually integrally associated with each other with the interposition of electrical insulating members so that through holes of the respective ion selective electrodes may define a flow passage for a liquid to be measured, and a flow type ion sensor using the same.The ion selective electrode and flow type ion sensor using the same of this invention allow the measurement in a smaller amount of the sample to be measured and are excellent in the adhesion of the ion sensitive membranes, therefore they have ' effects of a stable potential supply and a prolonged life time, and these industrial merits are highly great.
