Abstract

A flow system glass electrode in use for pH measurement, which houses the glass electrode body in a resin block to improve an impact resistance, the glass electrode body being sealed by a packing to be small-sized and improve the degree of freedom in the direction of the use, sample flow tubes each being equal in an inner diameter to a response film and separate from the glass electrode body in order to eliminate stagnation of a sample liquid, enable the measurement of a minute sample, and facilitate manufacture and assembly of the electrode, the sample flow tubes being connected with a liquid inlet and a liquid outlet at the glass electrode body through couplings respectively.
