Description
K502 K+ Electrode is an ion-selective electrode developed for potassium ion measurements in laboratory solutions. It provides a measuring range of 1 ~ 6 pK, equivalent to 1 ~ 10⁻⁶ mol/l, and functions across temperatures of 5 ~ 60 °C. The electrode is intended for pairing with the compatible reference electrode 6215 and features a cable connection ending in a BNC plug for direct attachment to standard meters. This K+ electrode from manufacturer APERA Instruments supports accurate potentiometric determination of potassium activity in research, process monitoring and quality-control environments. Delivered as a single piece, it offers a practical sensing element for laboratories that routinely assess free potassium ion levels. The defined concentration window, temperature capability and BNC interface allow straightforward incorporation into existing ion-selective electrode systems, enabling reliable data collection during aqueous sample analysis without elaborate setup procedures.
This article is part of pH electrodes & sensors, in pH & electrochemistry.

Questions about K502, K+ electrode
What is this article?
K502, K+ 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.
