Jinan Jingrui Analytical Instrument Company was established in 2006, focusing on the research and production of Kjeldahl nitrogen analyzer, sample pretreatment equipment, and high-end box type resistance furnace series products. Among them, the JK9880 series Kjeldahl nitrogen analyzer technology is at the leading level in China and has won honors such as the 2011 "BCEIA" Gold Award and the Ministry of Science and Technology's Science and Technology Innovation Fund. The company's entire product line has also passed the IS09001 international quality management system certification, CE EU certification, and "Double Soft Certification". Jinan Jingrui Company is one of the drafting and creation units of the national standard for "Fully (Semi) Automatic Kjeldahl Nitrogen Analyzer". The technical background for the creation of the standard is based on the technical condition "indication error" of our JK9880 series products (the new standard was implemented in February 2018). At the same time, the technology and process level of Jinan's elite Kjeldahl nitrogen analyzer series products have reached a relatively high level in China. Jinan Jingrui Company is one of the large enterprises in China that develops and produces sample pretreatment equipment, with an annual production and processing capacity of thousands of units (sets). In particular, the application of multiple patented technologies such as the "fully automatic sample digestion platform" represented by the wet process fundamentally solves the corrosion problem of such equipment. Jinan Jingrui Company is also a high-end box type resistance furnace production enterprise in China, with an annual output of nearly 4000 units and users all over the world. The "R&D type" series products have a design temperature of up to 1700 ℃, which is an ideal choice to replace imported products. Jinan Jingrui Company adopts a business model of independent brand promotion and OEM synchronous implementation. We welcome users and OEM manufacturers to come and guide, visit, and negotiate. We are willing to work hand in hand with partners and friends from all walks of life in society. Common development and progress! Our corporate vision is to provide accurate and intelligent analysis solutions, create value for our customers, align our business philosophy with technology and rigor, and simplify, standardize, and systematize our management philosophy for analysis and laboratory services
