Product Description

The Hanna Instruments HI 5315 is a reference electrode for ion selective electrode (ISE) half-cell electrodes with a double silver-silver chloride junction, polyetherimide (PEI) body, O-ring seal between sensor handle and cap, banana plug, 1m (3.3') coaxial cable, and is refillable. A reference electrode provides the electrolytic contact necessary to measure a voltage gradient across a measurement membrane, such as an ISE. Ion selective electrodes respond selectively to ions in the presence of other ions, and are commonly used for water testing, and to analyze biological samples in hydroponics, aquaculture, and agriculture. The double silver-silver chloride junction reduces sample solution ingress into the reference compartment for long electrode life in harsh environments. The 120mm high PEI body has an outside diameter of 12mm for use in moderately aggressive liquids, such as in wastewater, and for applications requiring stress resistance. The O-ring seal between sensor handle and cap provides protection against substances, and the electrode is refillable external reference to prolong electrode life. A banana plug provides tight cable connections. The electrode comes with 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.

Hanna Instruments manufactures analytical instrumentation and supplies, including pH meters, electrodes, chemical reagents, and buffer solutions. The company, founded in 1978 and headquartered in Woonsocket, RI, meets International Organization for Standardization (ISO) standard 9001.
