Description
F501 F⁻/reference/temperature combination electrode is a compact ion-selective combination sensor for fluoride determination that integrates reference and temperature elements. It offers a measuring range of 1 ~ 6 pF, corresponding to 10⁻¹ ~ 10⁻⁶ mol/l, and operates at temperatures from 5 ~ 45 °C. An integrated temperature sensor is included, the shaft is plastic, and connection is provided by cable with BNC plug. Supplied as 1 pc, this combination electrode from manufacturer APERA Instruments enables simultaneous fluoride, reference and temperature measurement in a single probe. The design simplifies laboratory setups by reducing the need for separate reference and temperature electrodes during pF-scale analyses. Suitable for analytical chemistry, water testing and quality-control applications, the sensor interfaces directly with meters accepting BNC connectors. Temperature capability up to 45 °C matches typical sample conditions for fluoride assays. Within the defined concentration window the electrode supports reliable potentiometric fluoride readings when proper calibration is performed, offering a practical all-in-one solution for routine ion-selective work requiring integrated temperature compensation.

Questions about F501, F- /reference/Temp. combination electrode
What is this article?
F501, F- /reference/Temp. combination electrode is the article on this page. Luminix Health distributes APERA Instruments for laboratory use. It sits in pH electrodes & sensors, inside pH & electrochemistry, in Lab instruments.
A pH electrode is a glass membrane and a reference. It is a consumable: the glass ages, the junction clogs, and the reading drifts. A refillable electrode and a gel electrode differ in how they are maintained. The connector has to match the meter. The electrode, not the meter, is usually what is wrong.
A pH meter is a voltmeter on a glass electrode. The voltage tracks hydrogen-ion activity, and the electrode is converted to pH only after it is adjusted with buffers of known value. Conductivity measures how well a solution carries a current, which for dilute salts tracks concentration. Dissolved oxygen and titration are further electrodes on the same idea: a sensor, a standard, and a reading that is only as fresh as the calibration. Buffer values and chemical identity sit on PubChem. Accreditation of the calibration laboratory is the field of BELAC and EURAMET.
