Introduction:
pH is measured potentiometrically when using an electrode. In other words, your measurement is based on an electrical signal. A potential develops across the glass membrane of a pH electrode when it comes in contact with a solution. This potential varies as the pH varies, but requires a constant second potential to compare the changes against. This is the function of the reference electrode, to provide a constant potential, regardless of pH.

About Us
Aurora Scientific Instruments (Shanghai) Co., Ltd is a solely owned Shanghai branch of the U.S Company, AlpHa Measurement Solutions. Aurora is specialized in manufacturing various electrochemical (E-chem.) sensors, not only for the U.S market, but also to be exported to Europe, America, Africa, Southeast Asia, Japan, and Taiwan markets to OEM for many name brand E-chem instrument manufacturers. Our E-chem sensors receive a warm welcome from the E-chem industry and are highly praised by domestic and overseas customers in matter of quality or in terms of appearance.
Seeing the demand for high performance E-chem sensors in the domestic market, Aurora has started to manufacture Aurora Brand electrodes to match various E-chem instruments made in China as well. To promote our domestic market electrodes, Aurora is providing the broad E-chem industry with the electrodes at a very competitive price for the domestic market while at the same time assuring you of the best quality.
Aurora can provide various industrial on-line electrodes and new model lab sensors manufactured by U.S. HQ to customers in China, such as pH, ISE, conductivity, DO and ORP electrodes.
