Ion Readings Right By Corning It's your choice for right pH readings from 0-14. Use our popular, fast response pH electrode, Corning, 476022, with our calomel internal reference electrode, Corning, 476002. They give right readings on most samples. Choose from a wide variety of pH, reference and combination electrodes for right pH readings on specialized applications. Use replaceable junctions (RJ's) for pH of junction clogging samples like molasses. Put them with Corning meters for the right pH reading for your needs.
