Ion-selective electrodes, SKU: 106651, Ion-selective electrodes

Potassium, Fluoride, Aluminium, Phosphate, Lithium, Ammonium, Copper, Cyanide, Chloride, Sodium, Calcium, Magensium, Silver, Nitrate, Bromide
Ion-selective and gas-sensitive electrodes are used for measuring the dissolved concentration of specific ions or gases in water. Similar to the pH electrode, the membrane interacts with the dissolved ions and delivers a concentration-dependent voltage signal that is converted to the corresponding measurement result.
