Ammonia is present in natural water resources and is also a product of microbial decomposition of proteins in decaying animals and plants. If the ammonia concentration in surface water shows the extent of pollution of domestic water. Ammonia and its compounds are also used as fertilizers. Generally, the most ideal resolution will not be lower than 0.1 mg/L, usually only 0.5 mg/L. The HI96715 ammonia nitrogen microcomputer analyzer has a CAL CHECK function, and the use of special NIST standard solution can check the performance of the instrument at any time to determine whether recalibration is needed. Convenient humanized confirmation operations can ensure good calibration of the instrument. The unique positioning mark design ensures the consistency of the cuvette position each time it is placed in the colorimetric groove. The larger diameter design of the cuvette facilitates the addition of samples and reagents. All instruments have been calibrated at the factory, and the excellent optical system design means that the instruments do not need frequent calibration. High-precision measurement results, ET99730 microcomputer multi-parameter analyzer, simple operation steps, excellent waterproof performance and light source dust-proof measurement system, make it widely applicable for laboratory and field measurements. Prompt information can guide daily operations, and the instrument has low battery indication function and automatic shutdown function.
