6 All are supplied with 1 m of cable and BNC plug Ion Selective Electrodes Polymer membrane consist of various ion-exchange materials in an inert matrix such as PVC, polythene or silicone rubber. The potential developed at the membrane surface is related to the concentration of the species of interest. Solid state utilise relatively insoluble inorganic salts in a membrane. Solid state exist in homogeneous or heterogeneous ms. In both types, potentials are developed at the membrane surface due to the ion-exchange process. Glass membrane are med by the doping of the silicon dioxide glass matrix with various chemicals. The most common of the glass membrane is the ph electrode. Glass membrane are also available the measurement of sodium ions. Gas sensing are available the measurement of ammonia, carbon dioxides and nitrogen oxides. These have a gas permeable membrane and an internal filling solution. The ph of the filling solution changes as the gas reacts with it which is detected by the built-in ph sensor. All models are double junction combination and have an epoxy body. The outer refillable reference chamber is silver-free and resists contamination. Dimensions:. Each electrode comes with electrolyte, reference filling pipette and manual.
