Oakton* pH Electrodes

The type of electrode you choose will depend upon your particular application. Use this as a reference guide.
Epoxy body, gel-filled electrodes: Economical. Choose single junction for general purpose or double junction for solutions containing sulfides or heavy metals, and calomel reference for solutions containing organics or tris buffers.
Epoxy body, refillable electrodes: Ideal for viscous or abrasive fluids. A spring-loaded sleeve design allows flushing out the reference junction to clean and renew it.
Glass body, refillable electrodes: Good for higher temperatures. Specially formulated glass prevents sodium error in high pH solutions.
Glass body, spear-tipped electrodes: Pointed tip allows insertion into semisolids. Good for food applications.
Submersible: Ideal for testing streams or tanks. Reinforced cap. Includes ten foot cable.
Direct connect: For use with pH Testr BNC.
Oakton* Universal Series and Specialty pH electrodes: For use with Oakton handheld and benchtop meters, the pHTestr BNC and virtually all other makes of pH meters with BNC input. Order temperature sensor (ATC probe) separately.
All-in-one electrodes: Combine pH measuring and reference cell with built-in temperature sensor for one probe convenience. BNC connector. Use with Oakton handheld and benchtop pH meters.
