Hua Guang located in the largest famous industry city of China--Shenyang. Shenyang not only has the earliest analysis instrument producing history record, it also represents the advanced technology of China in analysis technology and application science area.

In 1998, Hua Guang officially found with imported Japanese technology and production technics. With ten years research and invention, Hua Guang now becomes a professional lab instrument company who provides design, research, production, sales, service and expert laboratory solutions.

Hua Guang incorporated by HG precision instrument co., Ltd, HG analysis technology and application science academe and HG analysis testing centre. The production factory of HG located HG industry part in Shenyang development zones, the sales headquarter placed in Galaxy building in the economy centre

Excellent development capacity and production instruction technology dress the product of HG with outstanding technics and advance technology. With perfect modern quality examining system, it has been qualified by ISO9001: 2000 international quality management system.

HG major in producing large scale lab instrument which among the environment protection, health and safety, food detection, etc areas. Include atomic absorption spectrometer which enable to analysis and test trace elements and toxic metal, gas chromatography and high performance liquid chromatography which enable to test organic material in ration, character etc.

With excellent research capacity group endure HG with strong innovative ability, with years strive self improvement, our new invented LAB600 has been released which with 6 patents and numerous rewards. Its advanced technology and multiple functions impress BCEIA trade meeting and won the golden rewards which is the most effective and large professional analysis instrument trade meeting.

We freely guarantee the main board a whole-life of using which with wiring parts highly integrated in.
Our products are wildly used among metallurgy, petroleum, chemical industry, geology department, science research, university, food testing, health care and safety and environment protection etc. And honored trade our products to 20 national provinces and exported to whole Asian, Africa, and Europe countries.

We uniformly forces on building a harmonious environment between healthy life and healthy environment and donates our best technology support and services for this mission.

HG business object: providing professional integrative optimized laboratory solution.
