Product Description
The Hanna Instruments HI 72911D is a pH electrode for the HI 99141 portable pH meter and has a double polytetrafluoroethylene (PTFE) junction, Automatic Temperature Compensation (ATC), titanium body, flat tip, internal amplifier, Deutsches Institut fr Normung (DIN) connector, 1m (3.3') seven-pole cable, and operates in pressurized systems. 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 PTFE junction reduces sample solution ingress into the reference compartment for longer electrode life. The titanium body with flat tip is for use in for cooling towers and boilers. An internal amplifier provides a strong low impedance signal from the electrode to the HI 99141 portable pH meter. The electrode operates in pressurized systems up to 43.5 psi (3 bar). A DIN connector provides a tight cable connection and the electrode comes with a 1m (3.3') seven-pole cable.

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.
