For lab work or industrial testing that requires precise pH or potentiometric measurements? This is a Mercury/Mercury Oxide (Hg/HgO) reference electrode. It's especially suitable for measurements in alkaline solutions, offering good potential stability and reproducibility. You can choose between the R0502 model (with a double salt bridge) or the R0501 (single salt bridge). It uses a 1.0 mol/L KOH salt bridge solution and has a standard electrode potential of 0.098V at 25°C. Commonly used with pH meters, ion meters, potentiometric titrators, and electrochemical workstations. This is a specialized piece of laboratory equipment, so please ensure it meets the specific requirements of your application before purchasing.
