Shanghai Metallographic Environment Technology Co., Ltd. is committed to the manufacturing of industrial control intelligent equipment and comprehensive laboratory solutions. Its research directions mainly include the development and application of material physical and chemical property detection methods and equipment, the development and application of teaching and research experimental instruments, the research and practice of new isotope separation technology, the comprehensive utilization of seawater resources, the development of nano micro bubble generation devices, and the application of nano micro gas-liquid interface technology in soil remediation/river treatment/agricultural breeding wastewater treatment/facility agriculture intelligent equipment application practice and data collection. The company also participates in or leads the preparation/revision of some group standards, national standards, and ISO international standards, and provides testing services for dozens of projects such as contact angle, surface tension, interfacial tension, CMC, zeta potential, nano and micro bubble size and concentration to the outside world. In 2016, Shanghai Metallographic Environment Technology Co., Ltd. received financial support for its "Import Replacement Project for Physical Property Testing Instruments". The affiliated enterprises of Shanghai Metallographic Environment Technology Co., Ltd. also include: Shanghai Zhongchen Digital Technology Equipment Co., Ltd., Shanghai Metallographic Enterprise Management Co., Ltd., Shanghai Yisu Electronic Technology Co., Ltd., Shanghai Yisu Material Technology Co., Ltd., Shanghai Dongxing Business Exhibition Service Co., Ltd., Zhejiang Zhongchen Ecological Agriculture Co., Ltd., Zhejiang Zhongchen Instrument Manufacturing Co., Ltd., Napo Testing Technology (Shanghai) Co., Ltd., etc. Shanghai Metallographic Environment Technology Co., Ltd. and Shanghai Zhongchen Digital Technology Equipment Co., Ltd. have complete independent intellectual property rights to the physical property testing instruments and equipment developed and produced by them. The company continuously strengthens its advantageous position in six aspects, including underlying algorithms, patent groups and standards, modular design to provide users with autonomous and continuous expansion space, efficient non-standard customization based on 3D printing technology, a mobile engineer service network throughout the country, and strong cost-effectiveness. It has achieved "zero" accounts receivable: that is, all orders received by the company must be fully paid in advance before they can be delivered, installed, debugged, and trained within a few working days. This not only ensures that the company focuses on technology research and development and quality control, but also guarantees that users have the right to long-term after-sales service and continuous software and hardware upgrades.
