The Hanna Instruments HI 1280 is a pH electrode for the HI 98111 Piccolo tester with a single ceramic junction, Automatic Temperature Compensation (ATC), a polypropylene plastic body, an internal amplifier, and a multipin connector. 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. An internal thermometer sensor in this electrode provides ATC for accurate readings in fluctuating temperatures. The single ceramic junction provides long electrode life in harsh environments. The polypropylene plastic 50mm high body with 14mm outside diameter and 5.0mm spherical tip is for general purpose and field applications. An internal amplifier provides a strong low impedance signal from the electrode to the tester, and the multipin connector provides a tight connection.

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 hobb...
