  • Measurement range is 69,000 to 0.002 ppm, and main interfering ions are Li+, K+, and Ba+2
  • Electrode is 12mm in diameter and 145mm long, and has a 1m cable with a BNC connector for attaching to meters with a BNC connection
Additional Information

The Thomas 3401BN (4230B19) combination sodium ion selective electrode (ISE) has a glass membrane sensor for measuring the sodium (Na+) concentration in steam condensates, clinical analysis samples, serums, food, wine, glass, sea water, and other aqueous solutions. This combination electrode contains both the measuring half-cell and the reference half-cell to minimize electrostatic interference and provide consistent readings. Its glass membrane sensor is formulated for sodium ion measurement. The electrode's epoxy body is impact resistant, durable, and sealed and filled with an electrolyte solution gel for minimal maintenance.

The ISE has a measurement range of 69,000 to 0.002 parts per million (ppm), and its main interfering ions are Li+, K+, and Ba+2. It is 12mm in diameter and 145mm long, and has a 1m cable with a Bayonet Neill-Concelman (BNC) connector for attaching to meters with a BNC connection. The electrode operates in temperatures from 0 to 50 degrees C (32 to 122 degrees F). ISEs respond selectively to ions in the presence of other ions, and they are commonly used for water testing and analyzing biological samples in hydroponics, aquaculture, and agriculture, 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.
