PURPOSE:To exclude erroneous operation accompanied by manual switching operations, by correlating the measured data of inputted water contents and loads with associated tables in a memory part, judging the kind of sample grain, and automating the switching operation of equipment in correspondence with the kind of the grain. CONSTITUTION:Sample grain is mounted on a central part 6a of a lower electrode part 6. An upper electrode part 4 is lowered, and a load is applied to compress the sample. The load is detected and measured by a load sensor 42 comprising a gage 18. The load value and the water content value of the sample, which is measured by the upper and lower electrode parts 4 and 6, are sent to a multiplexer 32 and further sent to a CPU36 through an A/D converter circuit 34. The grain A, B... correspond to the measured data M of the inputted water contents. The measured data Wa, Wb... of the loads for the kinds of grains are compared with the actually measured load data W. For example when W=Wa, the measured data M of the water content is converted into the water content value Ma of the grain A. By the series of operations described above, the result that the sample to be measured is the grain A and the water content value is Ma is obtained. |
