Description
pH single-rod measuring cell SenTix 940-P is an IDS-technology combination electrode for laboratory pH measurement in a compact single-rod design. Digital IDS communication supports consistent signal transfer when the cell is connected to a compatible meter via a separately ordered cable or wireless module; neither cable nor wireless equipment is included with this article. The SenTix 940-P format is suited to everyday aqueous pH work in analytical, teaching, and quality-control laboratories that already operate WTW IDS systems. Manufacturer WTW positions this electrode within its SenTix range for users who need a replaceable single-rod measuring cell without permanently attached leads. One piece is supplied per pack, simplifying stock control for multi-instrument labs. The electrode weighs 0,248 kg, which favours comfortable handling during calibration, measurement, and rinsing steps. Model labelling on the product helps maintain traceability within electrode inventories and standard operating procedures. Pair the cell with the appropriate IDS interface accessories to complete the measuring setup and perform reliable pH determinations across typical laboratory sample matrices.
This article is part of pH electrodes & sensors, in pH & electrochemistry.

Questions about pH single-rod measuring cell, SenTix 940-P (IDS technology), 1 unit(s)
What is this article?
pH single-rod measuring cell, SenTix 940-P (IDS technology), 1 unit(s) is the article on this page. Luminix Health distributes WTW 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.
