Analysis of advantages of domestic electric instrumentation

First, China is a developing country. The instrumentation industry has a gap of 10-15 years compared with developed countries. However, in the developing countries, China is the largest and most complete and most powerful country in the instrumentation industry.

Second, China’s demand for instruments and meters is one of the fastest growing countries. The growth rate of instrumentation in the world is 3% to 4%. China has achieved an annual growth rate of more than 20% for four consecutive years, and some products already account for one-tenth of the world's total.

Third, at present, the instrumentation industry is a sector that directly competes with foreign companies. Foreign investment has entered the third phase in China. The first stage is the joint venture and technology export. The second phase of the joint venture between the 1990s and the 20th century is now entered into the third phase, which is dominated by wholly-owned and merged Chinese outstanding companies.

Fourth, some middle and low-end products already have scale advantages and international market competitiveness. For example, ordinary digital multimeters and other products account for a large amount of production in the world, and the production capacity of household electric meters accounts for 50% of the world. At present, China has become a power meter, microscope, telescope, thermometer, pressure gauge, water meter, gas meter, and optics. The export of high-end products, such as the production and export of components and other products, and container inspection equipment, have also begun to make breakthroughs.

The low noise issues of lasers are due to the competition of mode in Laser resonant cavity, which lead to high frequency jitter of output power. Through special design for laser resonant cavity and other components, the laser amplitude noise can be reduce efficiently. CNI Low Noise Laser can be widely applied to DNA sequency, cell sorting, spectrum analysis, interference measurement, laser holography, photo processing and biomedical and other fields.

CNI offers low noise lasers in wavelengths from ultraviolet to infrared (360~1550 nm).
