Ammonia is present 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 domestic water pollution. 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. 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, simple operating procedures, 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. The main performance features of HI93700 include:
- Compact design (PL3002), easy to hold;
- Simple operation, easily complete various operations;
- Clear and readable LCD display, convenient for quick data reading;
- Colorimetric cell positioning marks ensure consistency of measurements;
- Reagents are packaged in powder or liquid form. The precise dosage of reagents ensures good reproducibility;
- Automatic power-off mode to save electricity.
