Development trend and thinking of weighing instrument Market

The development of scientific instruments has become a national strategic measure In developed countries, the development of scientific instruments (electronic balance, electronic weighbridge, electronic hook scale) has shifted from spontaneous state to conscious and targeted government behavior The United States, Japan, Europe and other developed countries and regions have already formulated their own development strategies and targeted their goals, with special investment to accelerate the invention, development, transfer and industrialization of original instruments The developed countries, with their advanced scientific research level, long-term high-tech reserves, effective management system, the basis of widely occupying the world market, and strong economic and military strength, attempt to curb the independent development of scientific instruments in developing countries This situation is becoming more and more obvious, which should be paid more attention to 2 Today's remarkable development of science instrument technology Zui is in many fields directly related to human survival and development, such as biology, medicine, materials, aerospace, environmental protection, national defense and so on Research scale goes deep into mesoscopic (nano) And microcosmic, it is required not only to determine the element, group and content in the analysis object, but also to answer the valence state of atom, molecular structure and aggregation state, solid crystal form, state of intermediate product in short-lived reaction and excited state in the physical process of Biochemistry; it can not only provide the analysis data in free state, but also can be used for surface, inner layer and micro area analysis, even three-dimensional analysis Stereo scanning analysis and time-resolved data Therefore, it has become a trend to develop high-resolution, high selectivity, high sensitivity in vivo dynamic research technology, in-situ technology, non-contact (non-destructive) measurement technology and so on The development of ultra fast time resolution and ultra-high spatial resolution technology has become a new goal of instrument development The object and process of the study have changed from static to dynamic In the world, it is developing a flow analysis system integrating sampling, sample processing (production), automatic detection and analysis, and output of results, and developing field and real-time research means The bottleneck of complex system research, such as life science, is the lack of sensitive, effective and fast on-site or real-time research means The breakthrough to solve this problem lies in the development of new detection principles and new detection instruments 3 The development and production of instruments tend to be intelligent, miniaturized, integrated, chip based and system engineering, using modern micro manufacturing technology (optical, mechanical and electrical) , nanotechnology, computer technology, bionics principles, new materials and other high-tech development of new scientific instruments have become the mainstream, such as micro total chemical analysis system, micro laboratory, biochip, chip laboratory and so on For example, the developing chip type automatic analysis element not only has testing function, but also can perform separation, reaction and other operations Combining the functions of these chips will form a micro analysis instrument, and then form a chip laboratory Now, the devices used in gene and gene level research include: micro flow distribution device, micro electrophoresis device, micro polymerase chain reactor (PCR device, etc.) These separation and analysis components can be used in glass, fused silica or plastic, the size of which is like a chip, but they have some functions of "traditional" separation and analysis instruments On the basis of the high development of micro components and microprocessors, it seems that the research and development of small, cheap, accurate and reliable household and personal analytical instruments may have a large market capacity In addition, in some major scientific frontier research, the test and research methods have become major and complex scientific research projects, such as large-scale astronomical telescope, high-energy particle accelerator, aerospace remote sensing system, etc., which are all subsystem integration armed by many high-tech 4 Networking of test instruments: due to the improvement of automation and intelligence level of instruments, networking of multiple instruments has been promoted and applied, and new technologies such as virtual instruments and 3D multimedia have become practical Therefore, through the Internet Network, instrument users can exchange information and browse in different places, manufacturers can directly communicate with users in different places, and can timely complete such work as instrument fault diagnosis, guide users to maintain or exchange data of new instrument improvement, software upgrade, etc The operation process of the instrument is more simplified, and the function replacement and expansion are more convenient The network test system (instrument) is the inevitable way for the future test technology development.
