Description
Replacement standard electrode measuring 121 mm in length and 12 mm in diameter, fitted with a PVC cable of approximately 1000 mm for connection to the ad 140 pH instrument. Designed as a direct spare sensing element, it restores standard electrode function where the original probe requires renewal in routine pH measurement setups. The slender 12 mm body suits typical laboratory electrode holders and sample vessels used with benchtop pH meters. Cable length of about 1000 mm provides convenient reach between the measuring point and the meter without excessive slack. This replacement electrode from manufacturer Amarell is intended for maintenance of ad 140 pH systems in analytical, quality-control and general laboratory workflows that rely on consistent electrode geometry and cabling. Supplied as 1 pc, it supports uninterrupted pH determination once installed on the compatible meter. The format aligns with common electrode categories for pH work, offering a straightforward path to keep existing ad 140 pH equipment in service.
This article is part of pH electrodes & sensors, in pH & electrochemistry.

Questions about Spare standard electrode 121x12mm, PVC-cable c.1000mm, for ad 140 ph
What is this article?
Spare standard electrode 121x12mm, PVC-cable c.1000mm, for ad 140 ph is the article on this page. Luminix Health distributes Amarell 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.
