Page 9: Overview
Overview Overview Introduction This product is a detector for measuring of low conductivity sample. Measuring pH of low conductivity sample is quite difficult for the ordinary pH meter. It is necessary to reduce the impedance of the liquid by the neutral solution. The inner solution of the reference electrode leaks much more than the ordinary pH reference electrode and reduces the impedance of the sample. -
