The invention provides a high-precision moisture Raman system using monochromator. According to the invention, a scaling sample unit is added in an original moisture Raman system. Known Raman signal of the scaling sample unit is utilized as standard to carry out scaling for monochromator. A support which can move three-dimensionally also is added. Through the control of a computer and the movement of the three dimensional support detection key point changes freely between a laser radar unit and the scaling sample unit. Atmosphere detection is directly started after the completion of scaling by the monochromator. There is no need of other change of the original moisture Raman system. An error caused by the movement of moisture Raman system element is avoided and the accuracy of atmosphere detection is increased.
