Variations in density, temperature, granule size, ionic conduction, etc. cause a measurement error for all indirect methods for measuring loose materials moisture content.Multiparameter method has the potential to decrease or even eliminate the influence of all disturbing parameters on the measurement variable (moisture content) for every measurement method (i.e., capacitive, microwave, etc.), this reduces the measurement error.Application of multi-parameter method of moisture measurement is a result of developing opportunities in instrumentation design using fast computer equipment.A new microcontroller-based moisture meter was developed for loose materials with binary frequency measurement control и temperature compensation.It was estimated that the expected measurement error is within permissible limits.
