Description
CA502 Ca2+ Electrode is an ion-selective electrode intended for calcium ion determination in aqueous samples. It covers a measuring range of 1 ~ 5,3 pCa, corresponding to 10⁻¹ ~ 5×10⁻⁶ mol/l, and operates at temperatures from 5 ~ 60 °C. The sensor is designed for use with the matching reference electrode 6211 and connects via a cable fitted with a BNC plug. Its shaft is made of plastic, supporting straightforward laboratory handling. This Ca2+ electrode from manufacturer APERA Instruments suits routine potentiometric analysis in research, quality-control and environmental laboratories where free calcium ion activity must be quantified reliably. Supplied as a single piece, the electrode integrates readily into standard meter setups for ion-selective measurements. The combination of defined measuring range, temperature tolerance and BNC connectivity makes it a practical choice for workflows that require consistent calcium sensing without complex preparation steps.

Questions about CA502, Ca2+ electrode
What is this article?
CA502, Ca2+ 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.
