Combination Electrode, Ammonium (NH4+)

Oakton Instruments, 27504-00, Cole-Parmer Combination Ion-Selective Electrode (ISE) , Ammonium (NH4+) Features:Easily fit into small spaces - no additional reference electrode is neededBromide (Br-) ISE with blue epoxy bodyThese fast and accurate electrodes do not require an external reference-they're easier to use than separate sensing and reference half-cell electrodes. All Cole-Parmer electrodes are double-junction combination ion-selective electrodes and are convenient to use in places where two electrodes won't fit. All electrodes include a 30-mL bottle of the reference solution, a reference filling pipette, a 1-m cable, a BNC connector, and an instruction manual. Solid-state electrodes also have twelve polishing strips.Economy Epoxy Electrodes have a durable epoxy body and are well-suited for portable field applications. The outer reference chamber is silver-free and resists contamination. These electrodes are refillable.Laboratory Glass Electrodes are double-junction in design, with a glass body that provides high-quality measurements for your laboratory applications. Improved glass seal enhances performance and reliability. Sealed inner junctions and refillable outer junctions accommodate special reference fill solutions ideal for low-concentration measurements. Use electrodes with a meter that has a resolution of 0.1 mV for the most accurate results. Many meters in the "pH/Ion Meters" section have 0.1 mV resolution; several also give direct readings in ppm.
