They both include wires made of silver and coated with silver chloride. They contain glass tubes with options of pH 7 buffer and saturated potassium chloride respectively. There is a small bulb at the end of the sensor electrode which is made from a permeable glass membrane with silica and metal salts. This membrane is made very thin so regarding lower the resistance brought on by it. It is this bulb which is dipped in the wanted option in order to determine pH.
