PROBLEM TO BE SOLVED: To provide a sampling method, a sampling device and a sampling system, capable of sampling from a raw material without deviation, and capable of accurately comprehending characteristics of a population by shortening the time up to the measurement of a sample weight.SOLUTION: A sampling method includes: a weight measurement step of measuring a weight of a raw material; a primary acquisition step of acquiring a primary sample at a dropping port of conveyors 7a, 7b; a temporary placing step of transferring the primary sample to temporary receiving hoppers 30a, 30b; a secondary sample acquisition step of acquiring a secondary sample from the primary sample; and a measurement step of measuring the weight of the secondary sample. The sampling device and the system include; cutter samplers 20a, 20b provided on the dropping port of the conveyors 7a, 7b; pipe type samplers 40a, 40b for sampling the secondary sample from the primary sample which is transferred to the temporary receiving hoppers 30a, 30b; and a weighing device for measuring the weight of the secondary sample. |
