Perten Instruments AB offers Aquamatic 5100. In addition to moisture, the Aquamatic also determines specific weight and temperature. Other moisture meters need several calibrations per grain type, but according to the company the Aquamatic only needs one calibration for all grains and oilseeds. USDA research states that the 150 MHz technology and UMA (Unified Moisture Algorithm) reduces rebound effect and gives the true moisture content rather than the surface moisture content. All results are stored on the integrated flash memory and the Aquamatic is barcode reader-ready.
