Environmental Monitoring Instruments Status and Development Trend

At present, there are more than 140 manufacturers of environmental monitoring instruments in China with an annual production value of 480 million yuan, accounting for approximately 2.3 of the national environmental protection product output value. The main products of environmental monitoring instruments are various water pollution and air pollution monitoring, noise and vibration monitoring, radioactive and electromagnetic wave monitoring instruments. The environmental monitoring instruments such as soot sampler, flue gas sampler, total suspended particle sampler, oil analyzer, and sewage flow meter produced in China have approached or reached the international advanced level, occupying a large proportion in the domestic market. The domestically-adopted large-scale laboratories use atomic absorption, UV-visible spectrophotometers, gas chromatographs and other automatic monitoring technologies for monitoring instruments to a lesser degree, and key components still depend on imports. China's environmental monitoring instruments are mostly produced by small and medium-sized enterprises, and the products are basically concentrated in middle and low-grade environmental monitoring instruments, which are far from meeting the needs of the development of environmental monitoring in China. The main performances are: 1 low technical level, low level, serious repetitive production, poor scale efficiency; 2 poor product quality, unstable performance, poor consistency, short service life, high failure rate; 3 low research and development capabilities, The on-line monitoring instrument system has a relatively low production capacity and cannot meet the needs of the market.

Environmental monitoring and monitoring instrument development trends:

First, the development of narrow-area monitoring to all-round field monitoring;

Second, from labor-intensive to technology-intensive development;

Third, environmental monitoring instruments will develop environmental monitoring instruments in terms of high quality, versatility, integration, automation, systematization, and intelligence. This is the basis and technical support for environmental management. With the development of environmental protection in China, the environment in China The monitoring technology has also made great progress, and the production of environmental monitoring instruments has formed a certain scale;

Fourth, the development of simple ground environment monitoring combined with remote sensing environmental monitoring.
