In terms of the development concept of the enterprise, we also pay more attention to the overall planning and market layout. At the same time, adhering to the”4S” product research and development idea, paying attention to the protection of intellectual property rights, and actively exploring the domestic market, the market competitiveness and market share of pilot Lijia products have been continuously improved.

1. Technological Development

From the perspective of technological development, through innovative optical design, pilot Ricard not only makes the product performance more stable, but also significantly reduces the cost of the product, making the refractometer product miniaturized, even miniaturized; At the same time, combined with the design concepts of”big data application” and”Internet +”, it has filled many industry gaps and laid a solid foundation for the popularization, promotion and application of digital refractometer products.

2. Trade Development

From the perspective of trade, in the past, our medium and high-end instruments and meters were imported for a long time, and the high-end instruments and meters were almost monopolized by foreign companies. The world-renowned refractometer R & D and production manufacturers include atago in Japan, b+h in Germany, Anton Paar in Austria, METTLER TOLEDO in Switzerland, Rudolph company in the United States, etc. among them, atago in Japan has a significant advantage in China’s domestic market and is mainly sold through agents. In particular, sensor instruments and meters are not only expensive, but also more than 80%of them come from abroad.

Over the years, through our continuous efforts, we have not only greatly reduced the production cost of digital refractometer products, made the appearance design of products tend to miniaturization, but also solved the problems of large-scale production of products, so as to improve the competitiveness and market share of products in the domestic and international markets, and gained extensive praise from users at home and abroad. Let”made in China, invented in China” really go to the world!

3. Social benefits

For a long time, due to the weak technology research and development foundation and lack of brand awareness of domestic related enterprises in liquid measuring instruments, foreign refractometer products have occupied the vast majority of the domestic market of high-end instruments and meters. Facing this situation, we are deeply responsible. Although the overall level of measurement instruments and equipment in China does lag behind the international advanced level, especially the design level of optical measurement systems, we must meet the difficulties, break the technological monopoly of foreign enterprises, and create a national brand in the field of intelligent measurement in China.

In the face of such a gap, we need to increase and speed up investment, and pay attention to technological research and development and the transformation and upgrading of production lines. The instrument and meter industry is a long march for practitioners. We have been racing against time. Through more than 20 years of efforts, we have made great progress in the field of Refractometers. Our refractometer products have grown from scratch, from scratch to precision, and continue to move forward.

At the same time, the application field of refractometer products has also been expanded unprecedentedly. At present, the application fields include food processing, automobile, medical treatment, energy, textile, printing, chemical industry and other industries, as well as laboratories, universities, scientific research institutes and other units. The product can be used to measure the sugar concentration of food and beverage, measure the indicators of human urine, measure the parameters of battery electrolyte (battery power measurement and life diagnosis), measure the freezing point of automotive glass water and refrigeration fluid and the boiling point of brake oil, measure the indicators of diesel fuel added urea (AdBlue) and the quality of gasoline and diesel, etc. It not only breaks down industry barriers and refines user groups, but also achieves good social benefits.
