Shanghai Jing Hong Laboratory Instrument Co.,Ltd. Founded in 1996. At the same year,we researched and developed the four famous series “DHG series Heating and Drying Oven”, “DNP series Thermostatic Incubator ”, “DZF series Vacuum Drying Oven” and “DK series Thermostatic Water Bath”. Keeping on research and development of new technique and products, we also focus on quality consciousness of the staff to improve the quality of the products. We obtained the License of production Enterprise of Medical Apparatus, the ISO9001:2000 International quality system authentication, and CE Certification since 2000. Our products are on a good sale in domestic market, and about 20% of our products are exported ,At the 2002, we invest RMB10,000,000 in purchasing lanb of 22 ma, so as to establish first project of new workshop at 7000 square meters and plate manufacturer . In this way, we can start the mass production ourselves.

At present, our products cover 8 categories, 37 varieties and 152 specifications, Our company has lots of talent staffs specialized in design, produce, sale and service. All of us are trying our best to establish the famoud brand in laboratory instruments field.
