连华COD检测仪5B-3C

Medical wastewater contains various biochemical toxic and harmful substances such as bacteria, heavy metals, organic solvents, and acid-base solutions. If the above-mentioned substances are directly discharged, they will cause harm to the natural ecology and human living environment. China has clear discharge standards for medical wastewater. Lianhua Technology's response to the 'Emission Standards for Water Pollutants in Medical Institutions'GB18466-2005》Multiple portable and laboratory instruments and consumables are available to meet the testing requirements for the parameters involved

Lianhua COD detector 5B-3CThe principle adopted is to replace the spherical reflux tube with a glass burr reflux tube, and to replace the tap water cooling method with air cooling technology, which can not only save water and standardize the instrument, but also improve the efficiencycodThe safety of using the measuring instrument. The reagents used areLianhua Total Nitrogen Reagent LH-NT-100 and Lianhua COD Reagent LH-DEThe instrument is also equipped with an air pressure sampling device and an automatic zeroing burette, which simplifies the later titration operation procedures and improves the reliability of the method.
