USED - USED - IN GOOD CONDITION. PROB IS SEALED The Thermo Scientific Orion 815600 combination electrode measures pH with 0.01 precision in less than 30 seconds and has a double-junction reference for testing dirty water and solutions with heavy metals or organic compounds. This combination electrode contains both the measuring half-cell and the reference half-cell to minimize electrostatic interference and provide consistent readings. It has a durable, impact-resistant epoxy body and is refillable, allowing the filling solution composition to be adjusted to suit the sample requirements (electrolyte reference solution sold separately). The electrode measures pH from 0 to 14 and withstands temperatures from 0 to 100 degrees C (32 to 212 degrees F). It is 12mm in diameter and 120mm long, and has a 1m cable with a Bayonet Neill-Concelman (BNC) connector for attaching to meters with a BNC connection. pH electrodes measure the acidity or alkalinity of a substance and are commonly used by researchers, manufacturers, and hobbyists in hydroponics, aquaculture, agriculture, and wine-making, 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.
