Designed to make it quick and easy to choose the right pH electrode for any laboratory application, the Thermo Scientific Orion pH Electrode Selection Guide is an interactive guide that helps the user select the most appropriate pH electrode to meet his or her indicated needs and budget. Simply and intuitively, the guide asks an operator a series of questions about requirements—including the type of application, sample size, materials of construction and temperature compensation—and narrows the electrode choices from a field of hundreds to a few. It features the Orion pH electrodes, including ROSS electrodes.
