Compliance Voltage: How Much is Enough?
1 Feb 2017The compliance voltage of a potentiostat is the maximum voltage that the potentiostat can apply to the counter electrode in order to control the desired voltage in the electrochemical cell. When purchasing a potentiostat, you need to choose one with a high enough compliance voltage for your electrochemical cell, however the higher compliance value the higher the cost. This application note describes how to calculate how much compliance voltage you need for your electrochemical cell.

pH Meters and ElectrodesIon and pH meters are electrochemical equipment used to measure the pH (acidity or alkalinity) or specific ion concentration of a solution. Other meters can also measure the conductivity or dissolved oxygen content of a solution. pH meters, specific ion meters, conductivity meters and dissolved oxygen meters can come as benchtop or portable equipment. A meter’s electrodes can be replaced with easy to clean electrodes or electrodes for difficult media. pH, ion and conductivity meters are typically used in life science research, pharmaceutical testing, food and beverage, environmental and water analysis.
