Description
CombiCheck 80 14738 is a ready-to-use multi-parameter standard developed for laboratory use as both a standard solution and an addition solution. It supports photometric determinations of chemical oxygen demand (COD), nitrate and phosphate and is specified for use with COD test set 14691, nitrate test set 14764 and phosphate test set 14729. The multi-analyte format enables calibration, control and spike-addition checks from a single preparation, supporting reliable method verification in water, wastewater and process-analysis laboratories.
This article is part of Dissolved oxygen & multiparameter meters, in pH & electrochemistry.
Supplied as one piece with a net weight of 0,171 kg, the solution is ready for immediate application without further dilution or reconstitution. Covering COD, nitrate and phosphate in one standard helps reduce the number of separate reference materials required for the listed test kits and simplifies day-to-day quality-control routines. Packaging data describe a compact unit appropriate for typical laboratory storage and handling of ready-to-use analytical standards.
This CombiCheck 80 standard from manufacturer WTW - a Xylem brand is intended to work with the corresponding photometric test sets, contributing to reproducible analytical results when applied according to the kit instructions. It is aimed at laboratories that need a practical, ready-to-use multi-parameter reference for COD, nitrate and phosphate testing.

Questions about CombiCheck 80 14738, Multi-parameter standard solution, ready for use
What is this article?
CombiCheck 80 14738, 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.
