Lianhua Technology has developed the innovative Manometric Method BOD Apparatus based on the Manometric Biochemical Oxygen Demand technology. Since 1982, Lianhua Technology has been focusing on the global market and on Water Testing. They were the first to use the Manometric Technique to assess BOD Water Testing. The system evaluates sample for oxygen, determines the amount of oxygen depletion as well as the fuel-oxygen deflation and pressure variation.
