Description
CombiCheck 50 14695 is a ready-to-use multi-parameter standard designed for laboratory use as both a calibration standard and an addition solution. It is compatible with photometric test kits for ammonium (14739, 14752), nitrogen (14537, 00613) and chemical oxygen demand COD (14560). The multi-analyte format enables efficient verification of several key water-quality parameters from a single reference preparation, supporting routine quality control and spike-addition procedures. Supplied as one piece with a net weight of 0,171 kg (gross weight 0,19 kg), the standard is ready for immediate application in analytical workflows. This preparation from manufacturer WTW - a Xylem brand is intended for laboratories performing photometric determinations of ammonium, total nitrogen and COD in water and wastewater matrices. CombiCheck 50 14695 provides a practical multi-parameter reference solution that helps maintain consistent method performance and simplifies the handling of standard and addition solutions within environmental and process analytical laboratories requiring reliable multi-parameter checks.

Questions about CombiCheck 50 14695, Multi-parameter standard solution, ready for use
What is this article?
CombiCheck 50 14695, Multi-parameter standard solution, ready for use is the article on this page. Luminix Health distributes WTW - a Xylem brand for laboratory use. It sits in Dissolved oxygen & multiparameter meters, inside pH & electrochemistry, in Lab instruments.
A dissolved-oxygen meter reads oxygen in a liquid, optically or with a Clark cell. A multiparameter meter adds pH, conductivity or both on one instrument. The sensor cap or the membrane is the consumable. A reading in air and a reading in water are different calibrations.
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.
