Digital Chemical Oxygen Demand Analyzer: 30-Minute COD Testing

Lianhua Technology was the first to innovate on water quality testing 40+ years ago. The Digital Chemical Oxygen Demand Analyzer validates our commitment to excellence and our mission of protecting global water quality. Using the rapid digestion method of COD determination spectrophotometry (the method was detailed by our founder, Mr. Ji Guoliang) and determined COD levels in sewage and other water samples then and now. The method was first published in the American "CHEMICAL ABSTRACTS," and the method has been formalized in China as a national standard above which other methods compete. The method has been and is the gold standard by which other methods and products are gauged internationally. In the Beijing and Yinchuan, the internationally standardized R&D laboratories, as well as the cutting-edge manufacturing facilities, water testing products are continually improved for simplification and faster results. All water testing products are designed for accuracy. Lianhua products and the Digital Chemical Oxygen Demand Analyzer are used for environmental monitoring, petrochemic, and the food industry. Lianhua Innovation is a global environmental stewardship leader, and Lianhua products are distributed in over 300, 000 s. The Digital Chemical Oxygen Demand Analyzer is testament to Lianhua Innovation.
