General product information

Ion-Selective and Gas Sensitive Electrodes
Ion selective and gas sensitive electrodes allow quick and easy determination of concentration and activity of a variety of dissolved ions and gases.
Ion concentration measurement is vital in a wide range of applications, some common examples are calcium content of milk, chloride in food and fluoride in toothpaste.
To measure ion concentration you require either a portable pH/ion meter, SevenGo pro™ (SG8) with a Combination Electrode (DC series), or a bench meter, model SevenMulti™ (S80/S50),  linked to a reference electrode and an appropriate ISE electrode.

Two reference electrodes are available, InLab®Reference filled with 3 mol/L potassium chloride for routine applications, and InLab®Reference Pro with re-fillable bridge for applications where potassium chloride is incompatible with the sample.

If you would like more information on ion selective measurement see our 'Guide to Ion Selective Measurement'.
