Description

  • Probe measures dissolved oxygen levels in aqueous solutions.
  • Replacement probe for Milwaukee SMS600 and Mi605 meters (both sold separately).
  • Reinforced plastic body for durability with a PTFE membrane sensor.
  • Imported from USA.
The Milwaukee MA840 refillable polarographic probe has an oxygen-permeable polytetrafluroethylene (PTFE) membrane sensor for measuring dissolved oxygen (DO) levels in aqueous solutions. This is a replacement probe for the Milwaukee SMS600 and Mi605 meters (both sold separately). The probe contains a platinum cathode and a silver chloride anode which a meter polarizes so that oxygen passing through the membrane can be measured to produce stable, accurate readings. The probe has a reinforced plastic body for durability. The probe is 10" long with a tip that tapers from 1-1/2" to 3/4" in diameter, and it has a 3m cable with a 7-pin Deutsches Institut für Normung (DIN)-compliant connector for attaching to the meter. 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. Milwaukee Instruments manufactures electrochemical instrumentation and solutions for water analysis under the Milwaukee and Martini brands. The company, founded in 1998, is headquartered in Rocky Mount, NC. What's in the Box? ------------------ * Milwaukee MA840 probe * 3m cable
