Polymer electrodes consist of various ion-exchange materials in an inert matrix such as PVC, polythene or 44— silicone rubber. Solid state electrodes utilise relatively insoluble inorganic salts in a membrane. Glass membrane electrodes are formed by the doping of the silicon dioxide glass matrix with various chemicals. TWo versions available:
• sealecRISE2013…ISE3713)
• refillable with replaceable membrane (ISE6013…1SE77B)
Gas sensing electrodes are available for the measurement of ammonia, carbon dioxides and nitrogen oxides. These electrodes have a gas permeable membrane and an internal filling solution. TWo versions available:
