Ammonia exists in natural water resources and is also a product of microbial decomposition of proteins in decaying animals and plants. If the degree of ammonia concentration in surface water shows the extent of pollution of domestic water. Ammonia and its compounds are also used as fertilizers, VIC-711. Generally, the most ideal resolution will not be lower than 0.1mg/L, usually only 0.5mg/L. The Lovibond water quality analysis tester, according to international water quality testing standards, adopts microcomputer control technology, making measurements fast and accurate. The microcomputer concentration tester can measure one or more measurement items; with built-in measuring curves, reagents react with the samples to be measured, converting the absorbance of the sample for a specific wavelength into the concentration value of the parameter to be measured, and displaying the results of the sample through an LCD liquid crystal display. The sample cell adopts a sealed anti-pollution design, ensuring that there will be no pollution or damage to various precision components inside the instrument during the measurement process and daily management. Using specially designed patented LED light sources, stable light sources are provided at low energy consumption. User-friendly interface, TE412-L type precision balance, high-quality quality, excellent performance, simple and quick operation, and dual calibration functions of factory calibration and user-defined calibration, making the measurement accurate, stable, and reproducible.
