    Not sure which solution fits you business needs?


    After more than 15 years of precipitation and development, we have launched multi-generation products independently developed and produced. We have high-quality product production lines and professional R&D teams to bring efficient and reliable concentration process measurement and control solutions to customers.

    Chuyi Measurement and Control has won the honorary title of national high-tech enterprise, has a number of invention patents and software copyrights, fully introduced ISO9001, ISO14001 management system certification, and obtained CE certification.

    We have established good cooperative relations with customers in 200 countries and regions around the world, and established a complete after-sales service system to provide customers with pre-sales, sales and after-sales services professionally and efficiently.

    As a world pioneer in the field of optoelectronic measurement, CHUYI M&C reflect what we believe in: Built For Precision.The annual research and development expenses account for 30% of the turnover, and we never stop pursuing excellence.


    Inline refractometer for the petrochemical industry

    The application of inline refractometer in the petrochemical industry can optimize production processes, enhance product quality, and reduce production costs.

    Is it difficult to detect the black liquor?

    In the papermaking industry, monitoring the concentration of black liquor is pivotal for effective control. The most reliable approach involves utilizing online concentration measurement instruments such as inline refractometer

    What a near-infrared spectrometer can do

    The measurements are typically performed using a spectrometer and a detector capable of capturing near-infrared wavelengths.


    We have two production process production lines, namely dry method and wet method. In these two production lines, it is necessary to detect and control the concentration of DMF. One is to ensure the quality of the finished leather products, and the other is to recycle and reuse to achieve environmental protection. Require. After 3 months of use, the working efficiency of this online refractometer has exceeded expectations. We are also very satisfied with the solution provided by the manufacturer. It is a very pleasant cooperation.

    The control of the concentration of NMP solution will directly affect our production quality. It is very important to choose an online concentration meter with high precision, high efficiency and high adaptability for our lithium battery production line.

    In the past, we used the manual titration method to detect the concentration value of the solution in the production process, but in order to improve the production efficiency, we chose an Inline refractometer. This instrument has obvious advantages. It can not only detect the concentration value of the solution, but also automatically clean and replenish liquid Control has solved a lot of problems for us.

    We make beverages and syrups. At first we were skeptical and used an inline refractometer to test the Brix of the syrup. After a series of tests, we found that there was no problem and it could meet the sanitary requirements, so we used this inline refractometer. instrument.

    We often have to measure the concentration of NaClO in water, but our NaClO concentration is not high, and there is no problem of free alkali. This inline refractometer has a high efficiency for the detection of the concentration of a single component, and we are very satisfied.
