The Hanna Instruments HI 1006-3205 is a pH electrode for continuous in-line monitoring in industrial applications with a polytetrafluoroethylene (PTFE) junction, Automatic Temperature Compensation (ATC), a nontoxic polyvinylidene fluoride (PVDF) body, a self-cleaning flat tip sensor, HT (high temperature) glass bulb, 3/4" National Pipe Thread Tapered Thread (NPT) external threads, a 5m (16.4') cable, a Bayonet Neill-Concelman (BNC) connector, a built-in matching pin, 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. This electrode has a PTFE junction that reduces sample solution ingress into the reference compartment for longer electrode life. ATC is provided by a three-wire internal platinum Pt100 resistance thermometer for accurate readings in fluctuating temperatures. The PVDF body is nontoxic and compatible with food. The flat tip eliminates deposits that can foul the electrode. The HT glass bulb is for high temperature applications from 0 to 100 degrees C (32 to 212 degrees F). The 3/4" NPT threads on both ends ease installation. The electrode operates in pressurized systems up to 87 psi (6 bar). A BNC connector provides tight cable connections and an internal matching pin prevents problems caused by grounding loop current, such as electrode damage and fluctuating measurements. The electrode comes with a 5m (16.4') cable.

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.
