Shanghai Lianhua Industrial Co., Ltd.

Lianhua Technology is a manufacturer of water quality analyzer in China with almost 40 years. The factory locates in Beijing. The product series include chemical oxygen demand (COD) analyzer, biochemical oxygen demand (BOD) analyzer, ammonia nitrogen (NH3-N) analyzer, total phosphorus (TP) analyzer, total nitrogen (TN) analyzer and multi-parameter analyzer. We also can provide pH/dissolved oxygen/conductivity meter and other laboratory instrument for you. We have professional R& D personnel and after-sales engineers, and can provide customers with one-stop procurement services for water quality testing equipment. These products have been widely used in the pharmaceutical, chemical, printing and dyeing and water treatment industries. And they are popular in Southeast Asia, Africa, America, Europe and Australia.

Among them, COD / ammonia nitrogen / total phosphorus / total nitrogen use spectrophotometry. We have built a standard curve in the instrument. As long as we use our reagent, we can quickly detect COD / ammonia nitrogen / total phosphorus / total nitrogen in water. The BOD instrument uses a mercury-free differential pressure method. The results are obtained after 1-5 days of cultivation. It is safe, reliable, and simple to operate.
