Product Details


Product Description

The Thermo Scientific Orion 9179BNMD combination oxidation reduction potential (ORP) triode electrode with a temperature sensor measures dissolved oxygen in aqueous solutions to determine their contaminant levels and their ability to act as oxidizing or reducing agents. It has a wick-type single junction reference for clean water applications. The electrode comes with a built-in temperature sensor for automatic temperature compensation (ATC) with +/-0.2-degree C accuracy; an 8-pin mini Deutsches Institut für Normung (DIN)-compliant connector is provided for attaching to meters with temperature-reading capabilities. This combination electrode contains both the measuring half-cell and the reference half-cell to minimize electrostatic interference and provide consistent readings. The electrode's epoxy body is impact resistant, durable, and sealed and filled with an electrolyte solution gel for minimal maintenance.

The electrode withstands temperatures from 0 to 80 degrees C (32 to 176 degrees F). It is 12mm in diameter and 120mm long, and has a 1m cable with a waterproof Bayonet Neill-Concelman (BNC) connector for attaching to meters with a BNC connection. ORP electrodes, also known as redox electrodes, measure the ability of aqueous solutions to act as oxidizing or reducing agents, and they are commonly used in for water testing and food processing applications in hydroponics, aquaculture, and agriculture, among other applications.

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.
