Description
KCl solution 3 mol is a potassium chloride solution used to refill the protective cap of pH sensors with liquid. The 3 molar concentration supplies the electrolyte medium commonly required to keep the sensor cap filled during storage and handling so that the sensing element remains in contact with a suitable solution. Offered in a 250 ml pack, the product has a net weight of 0,315 kg and a gross weight of 0,315 kg. Listed as product type KCl solution and carrying the CPY4® registered trademark, this preparation from manufacturer Endress+Hauser originates from Germany and is intended for laboratory and process settings where pH electrodes must be kept ready for use. Filling the protective cap with 3 mol KCl solution is a standard maintenance step for many pH measurement assemblies. The solution belongs to the range of laboratory materials used for everyday sensor care whenever the liquid level in the protection cap needs to be restored.
This article is part of pH electrodes & sensors, in pH & electrochemistry.

Questions about KCL solution 3 mol, 250 ml
What is this article?
KCL solution 3 mol, 250 ml is the article on this page. Luminix Health distributes Endress+Hauser 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.
