Cole-Parmer® 12-mm High-Accuracy, Single-Junction, pH Electrodes

Economical and efficient combination—buy a protective housing assembly, then simply replace the electrode as needed

High-accuracy electrodes are perfect for testing where temperature variations make many pH electrodes unreliable. These single-junction electrodes feature an innovative design that stabilizes readings in less than 20 seconds, with an accuracy of ±0.02 pH! The pH value stays constant at any given temperature up to pH 13. Maximum pressure is 100 psi at 25°>C.
