Water Quality Bio-toxicity Online Monitor

Currently, online monitoring methods using physicochemical approaches for chemical substances are single-indexed and cannot fully reflect the additive, synergistic, and antagonistic effects in the water body. Therefore, it has certain limitations in reflecting the comprehensive toxicity of the water body. However, monitoring the bio-toxicity of water quality can accurately reflect the comprehensive toxic effects of pollutants on the water environment. The Water Quality Bio-toxicity Online Monitor uses bioluminescent bacteria as the test organism, responding quickly to pollutants in the water. The instrument is capable of measuring various water bodies and is highly sensitive to heavy metals, pesticides, sterilants, herbicides, and industrial chemicals. It can perform routine monitoring and early warning for sudden water pollution events in rivers, reservoirs, lakes, drinking water sources, etc.

Permanganate Index Water Quality Automatic Analyzer

The E310 Permanganate Index Water Quality Automatic Analyzer is a product independently developed by BESCIENT TECHNOLOGIES. It is based on the potassium permanganate oxidation method for measuring the permanganate index in water. It complies with the standards of the Ministry of Ecology and Environment of the People's Republic of China's "The technical requirement for water quality automatic analyzer of permanganate index" (HJ/T 100-2003). It also meets the detection needs of the "Environmental quality standard for surface water" (GB 3838-2002) for the permanganate index limit values in surface water. Using the potassium permanganate oxidation method, its results are highly consistent with the "Water quality - Determination of permanganate index" (GB 11892-89) method.

Portable Groundwater Dual-Pump Well Washing and Sampling Controller

Using advanced optical analysis and chromatography analysis technology, it can continuously and automatically monitor the concentration of pollutants in ambient air, such as PM2.5, PM10, NOx, SO2, O3, CO, and NMHC, 24 hours a day. The system is highly compatible, intelligent, and stable, and meets the relevant technical standards for national ambient air automatic monitoring systems.

Chemical Oxygen Demand Water Quality Automatic Analyzer

The C310 Chemical Oxygen Demand Water Quality Automatic Analyzer is a product independently developed by BESCIENT TECHNOLOGIES. It operates based on the principle of potassium dichromate high-temperature digestion oxidation spectrophotometry. After undergoing pretreatment, the water sample is oxidized by potassium dichromate under high temperature and high pressure conditions. The Chemical Oxygen Demand (COD) content is then quickly determined using a spectrophotometer. The principle employed by the instrument complies with standards such as the "Water quality - Determination of the chemical oxygen demand - Dichromate method" (HJ 828-2017) and the "Water quality－Determination of the chemical oxygen demand－Fast digestion - Spectrophotometric method" (HJ/T 399-2007).

Ammonia Nitrogen Water Quality Automatic Analyzer (Ammonia Gas Sensing Electrode Method)

The E310 Ammonia Nitrogen Water Quality Automatic Analyzer, developed independently by BESCIENT TECHNOLOGIES, utilizes the ammonia gas sensing electrode method to measure the ammonia nitrogen content in water. This analyzer meets the standard requirements of the "Technical specifications and test procedures for water quality on-line automatic monitoring equipment of ammonia" (HJ/T 101-2003) set by the Ministry of Ecology and Environment of the People's Republic of China. It also satisfies the detection needs for ammonia nitrogen limit values in surface water as per the "Environmental quality standard for surface water" (GB 3838-2002). The analyzer employs the ammonia gas-sensitive electrode method.

Ammonia Nitrogen Water Quality Automatic Analyzer (Salicylic Acid Spectrophotometry)

The C310 Ammonia Nitrogen Water Quality Automatic Analyzer is a product independently developed by BESCIENT TECHNOLOGIES. It utilizes the salicylic acid sodium colorimetric method to measure the ammonia nitrogen content in water, including both surface water and wastewater. Under alkaline conditions and in the presence of a catalyst, ammonia nitrogen, which exists in the form of free ammonia or ammonium ions, reacts with salicylate to form a colored complex. The analyzer determines the ammonia nitrogen concentration based on the intensity of the color of this complex. The principle employed by the instrument complies with the "Water quality - Determination of ammonia nitrogen - Salicylic acid spectrophotometry" (HJ 536-2009) set by the Ministry of Ecology and Environment of the People's Republic of China. Factors such as excessive calcium and magnesium ions, residual chlorine, or turbidity may interfere with the measurement. Depending on the complexity of the on-site testing conditions, corresponding pretreatment systems can be optionally equipped.
