HK-8520 Ammonia Nitrogen Analyzer

The HK-8520 ammonia nitrogen analyzer is a laboratory instrument independently developed by Beijing Huake Instrument Technology Co., Ltd. for measuring ammonia nitrogen in water samples,Widely used in various fields such as education, scientific research, drinking water treatment, wastewater treatment, surface water and groundwater detection, industrial process control, and product quality control for ammonia nitrogen measurement.

HK-8520 adopts Nessler's reagent spectrophotometric method (HJ)

535-2009) measurement shows that ammonia nitrogen in the form of free ammonia or ammonia ions reacts with Nessler's reagent to form a yellow brown complex, and the color of the complex is proportional to the content of ammonia nitrogen.₃Ammonia nitrogen in water refers to ammonia (NH)₄^{）Or ammonium (NH)}+

）Ammonia compounds that exist in ionic form. Ammonia nitrogen is the most harmful form of nitrogen among all types, and is a sign of water pollution. Its harm to the aquatic ecological environment is manifested in multiple aspects. Like COD, ammonia nitrogen is also a major oxygen consuming pollutant in water bodies. Ammonia nitrogen oxidizes and decomposes dissolved oxygen in water, causing the water to turn black and odorous. Non ionic ammonia in ammonia nitrogen is the main factor causing toxicity to aquatic organisms, with significant toxicity to aquatic organisms, dozens of times greater than ammonium salts. In the presence of sufficient oxygen, ammonia nitrogen can be oxidized by microorganisms to nitrite nitrogen, which is then decomposed into nitrate nitrogen. Nitrite nitrogen combines with proteins to form nitrosamines, which have carcinogenic and teratogenic effects. Meanwhile, ammonia nitrogen is a nutrient in water bodies, which can provide a source of nutrients for algae growth and increase the likelihood of eutrophication in water bodies.

The first laboratory ammonia nitrogen analyzer to use touch screen operation, with a beautiful and elegant interface, simple to use, rich and intuitive display content.

A 7-inch LCD screen with the option to choose between Chinese or English.

The instrument is equipped with a constant temperature system, effectively avoiding interference from environmental temperature changes.

The light source adopts imported monochromatic photodiodes, which have excellent monochromatic performance, concentrated energy, stability, and low power consumption.

Adopting an optical path system ensures the accuracy and stability of the measurement.

Calibrate at one, two, or multiple points to ensure measurement accuracy.

The ratio elimination method greatly improves the long-term stability of the instrument.

Communication function: The stored measurement data can be exported through the USB interface.
