Hanna HI73127 Electrode (spare), pH Electrode with Pin Connection 0-14pH
- Replacement pH electrode for HI 98127, HI 98128, HI 98121, HI 98129, and HI 98130 testers
- Extendable cloth junction prolongs electrode life
- Stainless steel round connector eliminates bent or broken pins during electrode replacement
The Hanna Instruments HI 73127 is a replacement pH electrode for Hanna pHep 4, pHep 5, and Combo testers and has an extendable cloth junction and a stainless steel round connector. 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. This electrode has an extendable cloth junction to prolong electrode life. The stainless steel round connector eliminates bent or broken pins during electrode replacement. The electrode works with the HI 98127, HI 98128, HI 98121, HI 98129, and HI 98130 testers.
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.
