pH & electrochemistry

This category is split by function. Instruments are in pH meters, with portable, pocket and benchtop models. Electrodes and sensors have their own page, as do conductivity meters, oxygen and multiparameter meters, and titrators. Holders, storage solutions and other accessories are in pH and electrochemistry accessories. Calibration buffers and conductivity standards are grouped separately as well. If you are setting up a new measuring point, start with the meter and then add electrode, buffers and storage solution. Tell us what you measure and we will send one list: sales@luminixhealth.com.

For most aqueous solutions, a standard glass electrode is the right choice. For small volumes and narrow tubes, choose a micro-electrode with a thin shaft. For semi-solid samples such as cheese, meat, gels or soil, a penetration electrode with a pointed tip goes into the sample. Check on the product page that the connector fits your meter. Options are in pH electrodes and sensors. Whatever you choose, calibrate with at least two buffers around your expected value, from pH buffers and conductivity standards. Describe your sample to sales@luminixhealth.com.

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.
