We realized the improvement of a dielectric moisture meter in the form of elevation of its sensitivity to moisture with preservation of the independence of the results of measurement of the mass of the investigated material. In the improved meter, the moisture is found from the ratio of the sum of increments of the reactive and active components of the admittance of the capacitor sensor of moisture meter caused by placing the investigated material inside the capacitor to the difference between these increments or from the ratio of some other combinations of these increments. Both these ratios and the ratio of initial increments are independent of the mass of investigated material but much stronger depend on its moisture content. In practice, the application of these moisture meters can simplify the procedure of measurements and increase their accuracy.
