Lianhua Technology is one of the first companies focusing on the water quality testing industry. We focus on the development of the Laboratory Water Quality COD Spectrophotometer. Starting from 1982 we built and expanded on R&D laboratories and production facilities which attained international recognition. We are one of the few COD spectrophotometers that employ a rapid digestion method which ensures that our clients receive accurate COD results in under 30 minutes. Quick and compliant results are a necessity for the petrochemical and the food processing industries and municipal sewage treatment. Currently, our instruments are able to assess in excess of 100 water quality parameters. The Protection of Water Quality is our motto. Lianhua Technology is proud to contribute to global environmentally friendly efforts!
