Abstract
A sensor for measuring pH and conductivity for liquids is disclosed. The sensor includes a housing having a pH cell and a conductivity cell. A pH fluid flow path is defined between a pH cell fluid inlet and pH cell fluid outlet. An aperture within the pH cell is adapted to receive an electronic pH probe therein. The aperture is configured to position an end of the pH probe having a pH sensing area therein and juxtaposition to the pH fluid flow path so that fluid flowing within the flow path is exposed to the pH sensing area of the electronic pH sensor. A conductivity cell is adapted for placement of a conductivity sensor therein. The conductivity sensor is disposed between a conductivity cell fluid inlet and conductivity cell fluid outlet so that fluid flowing therethrough contacts the conductivity sensor.
