For study of total inaccuracy in the measurement of loose material moisture it was used the method of optimum experiment planning by price expenses. The mathematical model of dependencies between measurement inaccuracy and sort of the material, the temperature and moisture was received. The given model has allowed to value the degree and nature of the each factor influence for total the measurement inaccuracy of the loose material moisture and can be used for introduction the necessary adjustments to the measurements result. The using of the mathematical dependencies has allowed to reduce inaccuracy of the measuring converter to the level ΔW = 0,24%.
