Choose from a variety of unique electrode designs for use in tough industrial environments. All models feature BNC pH connectors to match a variety of meters and controllers. Electrodes with temperature compensation feature 100 Ω RTD temperature elements with mini-audio plug connections. Flat surface does not collect suspended solids—fluid flow across the electrode provides a cleaning action that extends electrode life and improves performance. Electrodes feature a Viton® O-ring to hold glass bulb in place.
