HK-8520 ammonia nitrogen analyzer Introduction:
HK-8520 ammonia nitrogen analyzer is a laboratory instrument independently developed by Beijing Huake Instrument Technology Co., Ltd. to measure ammonia nitrogen in water samples, widely used in education, scientific research, drinking water treatment, wastewater treatment, surface water, groundwater detection and industrial Ammonia nitrogen measurement in different areas such as process control and product quality control.
HK-8520 is measured by Nessler's reagent spectrophotometry (HJ 535-2009). Ammonia nitrogen in the form of free ammonia or ammonia reacts with Nissl's reagent to form a yellow-brown complex. The chroma of the complex is The content of ammonia nitrogen is proportional to.
Ammonia nitrogen in water refers to the combined ammonia in the form of ammonia (NH3) or ammonium (NH4+) ions. Ammonia nitrogen is the most harmful form of various types of ammonia gas. It is a sign of water pollution, and its harm to the water ecological environment is manifested in many aspects. As with COD, ammonia nitrogen is also the main oxygen contaminant in the water. Ammonia nitrogen decomposes the dissolved oxygen in the water, causing the water to become dark-smelling. Non-ionic ammonia in ammonia nitrogen is the main factor that causes aquatic organism poisoning, and it is more toxic to aquatic organisms. Its toxicity is several ten times larger than that of ammonium salt. In the case of sufficient oxygen, ammonia nitrogen can be oxidized by microorganisms to nitrite nitrogen, and then decomposed into nitrate nitrogen. Nitrite nitrogen combines with proteins to form nitrosamines, which have carcinogenic and teratogenic effects. Colleague ammonia nitrogen is a nutrient in the water body, which can provide a nutrient source for algae growth and increase the occurrence of eutrophication of the water body. Features:
1. The first laboratory ammonia nitrogen analyzer with touch screen operation has a beautiful and easy-to-use interface and is easy to use. The display content is rich and intuitive.
2. 7 inch LCD screen, select Chinese or English.
3. The instrument is equipped with a constant temperature system to effectively avoid the interference of ambient temperature changes.
