The Hanna Instruments HI 1131P is a combination (full-cell) pH electrode with a single ceramic junction, glass body, spherical tip, Bayonet Neill-Concelman (BNC) plus pin connector, and is refillable. A pH electrode is commonly attached to a pH meter to measure the pH of a substance such as water, food, beer, or wine in lab, industrial, and food applications. The single ceramic junction of this electrode has a flow rate of 15 to 20 microliters per hour. The ceramic junction is for long electrode life in harsh environments and for general laboratory applications and beer testing. The 120mm high glass body has an outside diameter of 12mm and a 9.5mm diameter spherical tip for use in highly corrosive environments. The electrode is refillable to prolong electrode life. A BNC plus pin connector provides tight cable connections and prevents grounding problems. The electrode comes with a 1m (3.3') coaxial cable.
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), and ion selective electrode (ISE). Electrodes can be half-cell or full-cell (also called combination) types. 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. 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.
