Shenzhen Changhong Technology Co., Ltd. is a high-tech enterprise founded in 2002. For more than 20 years, we have been committed to the research and development, production and sales of hundreds of water quality monitoring instruments such as COD determinators, ammonia nitrogen determinators, total phosphorus determinators, total nitrogen determinators, and various water quality heavy metals and inorganic compounds. Product technology involves computer, MCU software and hardware, optics, chemical analysis and other technical fields. The company's current products mainly include: COD tester, ammonia nitrogen tester, total phosphorus tester, total nitrogen tester, turbidimeter, residual chlorine tester, copper, iron, nickel, zinc, hexavalent chromium, nitrite, cyanide, sulfide, iodide, volatile phenol, hydrazine, aniline and other monitoring instruments for hundreds of substances in water. At the same time, it produces instruments for measuring physical parameters in water such as pH, conductivity, dissolved oxygen, turbidity, chroma, and total hardness. The company's products have been sold all over the country. Currently, there are more than 8,000 domestic customers, located in more than 20 provinces, municipalities and autonomous regions across the country, and exported to Thailand, Indonesia, Singapore, Europe and the United States and other countries. It has formed a good reputation among users and has become the leader in the domestic water quality testing instrument industry with the most complete varieties, the most stable product quality, and the best comprehensive performance indicators. The "Shenchanghong" brand has also become a well-known brand in my country that independently produces water quality testing instruments. The company has been focusing on product quality management and new product research and development for many years, and the stability, repeatability and operability of its main products are in a leading position in China. The comprehensive performance is close to or even partially beyond the most well-known foreign brands, and more than 8 newly developed products are released every year. Product sales steadily occupy the market at an annual growth rate of more than 30%. Changhong Technology is becoming a well-known enterprise in China's water quality testing instrument industry in a way of "active innovation, quality priority, continuous progress, and steady advancement".
