Description
The Sensorex series S200C combination electrode has a single-junction reference for measuring the pH of aqueous solutions in clean water applications. This combination electrode contains both the measuring half-cell and the reference half-cell to minimize electrostatic interference and provide consistent readings. Its epoxy body is impact resistant, durable, and sealed and filled with an electrolyte solution gel for minimal maintenance. The electrode has a measurement range of 0 to 14 pH and withstands temperatures from 0 to 70 degrees C (32 to 158 degrees F). It is 12mm in diameter and 150mm long, and it has a 30-inch cable with either a Bayonet Neill-Concelman (BNC) connector or a US standard connector for attaching to compatible meters. It comes with a soaker storage bottle for storing and conditioning the electrode between uses. pH electrodes measure the acidity or alkalinity of a substance and are commonly used by researchers, manufacturers, and hobbyists in hydroponics, aquaculture, agriculture, and wine-making, 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. Sensorex manufactures pH, oxidation-reduction potential (ORP), and conductivity sensors, as well as other analytical sensors and accessories. The company, founded in 1972 and headquartered in Garden Grove, CA, meets International Organization for Standardization (ISO) standard 9001:2008, and is compliant to the European Union directives on Waste Electrical and Electronic Equipment Directive (WEEE) and Restriction of Hazardous Substances (RoHS).
