Beijing Lian Hua Yongxing Science and Technology Development Co., Ltd., is one of the pioneers manufacturers which develop water quality monitoring instrument in China. In 1982, The company manufactured the first COD catalytic rapid analyzer ,which shortened the time of reflux from 2hrs to 10 minutes. This method was included in American《CHEMICAL ABSTRACTS》, and got an Award of the updated contribution for the world's CHEMICAL industry in 1984. Because of the 30 years of continuous technological updates, COD catalytic rapid analyzer has been used as one of the standard instruments of Environmental Protection Monitoring station of water chamber and LianHua Technology has been a famous brand of national environmental monitoring instruments industry in china.
