Problems solved by technology

Most of the above existing technologies are aimed at improving the efficiency of nuclear magnetic resonance measurement and improving the reliability of the instrument, but there is no detection and calibration of the performance index and field working characteristics of the nuclear magnetic resonance water finding instrument. One instrument measures one type of data, it is not easy to share resources, data sharing, and the stability and reliability of the instrument are also difficult to guarantee
