                  JF-5 type trace water measuring instrument with Coulomb method


                  JF-5 Coulomb method micro water meter

                  Coulomb method for trace water analyzer is by Daqing City, Instrument Manufacturing Co., Ltd. to absorb domestic and foreign each instrument, the newly developed, with the international advanced level of modern analysis instrument. According to the principle of coulomb titration, the series instrument adopts microcomputer automatic control, compared with similar advanced products at home and abroad. It has the advantages of high sensitivity, fast speed, short balance time, accurate and reliable analysis results. Is the oil, chemical, electric power, environmental protection, medicine, scientific research and other departments of the first choice of high-quality analytical instruments.

                  With a new design concept, to adapt to the international trend, using split design, automatic man-machine menu dialog, full keyboard operation, can be connected to the computer, data processing, storage in the special software operation, small size, high degree of integration of the line. With a strong blank deduction function, the electrolytic cell is designed to prevent moisture intrusion, which greatly eliminates the influence of humidity on the analysis process.

                  I will continue to launch a series of new products, in order to adapt to the needs of different types of users, more embodies the human nature of analytical instruments, intelligent.

                  Instrument meets the standards:
