The Hanna Instruments HI 1219 is a pH electrode with a cloth junction, polypropylene plastic body, Deutsches Institut für Normung (DIN) connector, and operates in pressurized systems with the HI 981408 pH tester. 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 cloth junction of this electrode reduces contamination. The polypropylene plastic body with 240 mm (9.4") probe length is for use in fertilizer solution in tanks and vats. The electrode operates in pressurized systems up to 43.5 psi (3 bar). A DIN connector provides tight connection with the meter.

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 da...
