About Oakton WD-35812-02 Ammonium NH4+ Double-Junction
The Oakton refillable double junction combination ion selective electrode (ISE) measures the ion concentration in aqueous solutions, and has an epoxy body for impact resistance and durability. This combination electrode contains both the measuring half-cell and the reference half-cell to minimize electrostatic interference and provide consistent readings. The double junction protects against silver wire contamination and helps prevent clogging in dirty water and solutions with heavy metals or organics. The electrode is available in a variety of models that measure specific ions to suit different applications. It is 12mm in diameter and 110mm long, and has a 3-foot cable with a Bayonet Neill-Concelman (BNC) connector for attaching to meters with a BNC connection. The electrode comes with a 15 mL bottle of electrolyte solution and a pipette for refilling. The filling solution composition can be adjusted to suit the sample requirements. ISEs respond selectively to ions in the presence of other ions, and they are commonly used for water testing and analyzing biological samples in hydroponics, aquaculture, and agriculture, among other applications. The electrode is for use with the Oakton Ion 510, pH/Ion 2100 Bench-top, or Ion Acorn meters. It can also be used with any ion meter, or any other meter with a 0.1mV resolution. An electrode, also called a sensor or probe, is an instrument used with a meter to test and measure parameters of a substance. All electrodes are probes or sensors, but not all probes are electrodes or sensors. Probes, such as temperature probes, are used to penetrate a material for measurement. Common electrode types are pH, total dissolved solid (TDS), oxidation reduction potential (ORP), and ion selective electrode (ISE). They come in standard models or in all-in-one (sometimes called 3-in-1) models, which have a built-in temperature sensor for automatic temperature compensation (ATC). Electrodes can be half-cell or full- (also called combination) cell type. They can be refillable or non-refillable. Housing material is typically glass or epoxy, and sensors are commonly made with stainless steel or a glass bulb. pH electrodes, which measure the pH of a substance, often have a glass bulb. The bulb senses hydrogen ions, and generates a millivoltage that is picked up by the filling solution and transferred to a wire that connects to the pH meter. ORP, also known as redox, electrodes measure dissolved oxygen in aqueous solutions to determine the level of contaminants and their ability to act as oxidizing or reducing agents. Ion selective electrodes (ISEs) respond selectively to ions in the presence of other ions. Electrodes are commonly used by researchers, manufacturers, and hobbyists in a wide variety of industries, such as aquaculture, agriculture, chemistry, food and beverage, wine-making and water-testing, and for scientific applications. An electrode can be used with a datalogger to assist in temperature measurement. Oakton Instruments manufactures scientific instruments for research, industrial, and educational uses. The company, founded in 1991 and headquartered in Vernon Hills, IL, specializes in meters, electrodes, and transmitters. What's in the Box?
