Description
pH electrode for vials and test tubes with 1 m cable and BNC connector is a combined glass pH electrode with a single ceramic junction and refillable construction. Its slim body and spherical tip of 5 mm diameter are designed for measurements in reagent tubes, test tubes and small vials where standard sensors cannot reach. The single Ag/AgCl reference system uses 3,5 M KCl + AgCl electrolyte and delivers a junction flow rate of 15–20 µL/h. Measuring range covers pH 0 to 12, with a recommended operating temperature of −5 to 70 °C and a maximum pressure of 0,1 bar. A coaxial 1 m cable terminates in a BNC connector for straightforward connection to compatible meters. This electrode from manufacturer Hanna Instruments includes neither a built-in temperature sensor nor an amplifier, keeping the assembly compact for narrow vessels. Pack size is one piece; net weight is 0,28 kg and gross weight 1,28 kg. Ideal for routine laboratory pH work in confined sample volumes that require a slender, refillable glass sensor geometry.
This article is part of pH electrodes & sensors, in pH & electrochemistry.

Questions about pH electrode for vials and test tubes, 1 m cabel, BNC
What is this article?
pH electrode for vials and test tubes, 1 m cabel, BNC is the article on this page. Luminix Health distributes Hanna 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.
