Today, water is considered one of the scarcest natural resources on earth. It is important for humans, animals and plants. Depending on the quality of the water, it can be a source of life and health, or a source of disease and death. In recent years, increasing environmental degradation brought about by development, population growth and climate change has increased the need for researchers to study its negative impact on the environment, especially on water sources and their effects. Growing water pollution in oceans, lakes and rivers has prompted a need for more advanced methods in environmental monitoring systems worldwide, especially in the field of water quality monitoring. Under such large environmental conditions, JXCT independently developed water quality monitoring equipment and water quality monitoring systems to help people better complete water quality monitoring work, and better understand water quality conditions, which can be widely used in aquaculture water monitoring, swimming pool water monitoring, Water quality monitoring in places such as rivers and lakes.
Water quality monitoring is important, and JXCT helps
After years of research and the joint efforts of a strong R&D team, JXCT has developed a water quality monitoring system that can be monitored in real time, which can be applied to remote rivers, lakes, coastal areas and other water bodies. The main hardware of the system consists of off-the-shelf electrochemical sensors, microcontrollers, wireless communication systems, and custom-made buoys. It detects monitoring of water temperature, dissolved oxygen and pH, etc. at pre-programmed time intervals
The Multi-parameter water quality detector can freely match the measurement items according to the user's needs; the whole machine adopts the integrated design of the mold, and the appearance is fashionable; the application of the new touch screen menu operation technology realizes the practical and intelligent functions of the instrument, and has acid and alkali resistance, corrosion resistance, etc. The portable water quality analyzer can monitor water quality PH, ammonia nitrogen, total phosphorus, dissolved oxygen, turbidity, water level, chlorophyll and other parameters, supports free customization of parameters, portable and lightweight, plug and measure.
COD spectrophotometric detection: The study found that organic matter has a maximum absorption value in the ultraviolet region of 254 nanometers, so the absorbance at this wavelength can be measured. Suspended matter absorbs visible light at 900 nanometers, while the absorption mechanism of organic matter is almost zero, so it can be divided into two ways Light, the COD value of water quality can be obtained by measuring the degree of absorption of the two paths of light. BOD detection principle: The tryptophan in the water is excited by ultraviolet light to produce fluorescence. The detector detects this fluorescence signal and the sensor's built-in correction parameters convert the tryptophan fluorescence signal into related biochemical oxygen demand, using tryptophan indirectly By measuring BOD, the BOD value of water quality can be obtained.
Water PH sensor is one of the intelligent online chemical analysis instruments. It can continuously monitor data through the transmission output and connect the recorder to realize remote monitoring and recording. It can also be connected to the RS485 interface through the MODBUS-RTU protocol for easy connection Enter the computer to realize monitoring and recording.Water quality PH sensors are widely used in continuous monitoring of pH and temperature in solutions such as thermal power, chemical fertilizers, metallurgy, environmental protection, pharmaceuticals, biochemistry, food and tap water.
