1. Dimensions (length x width x height): 410mm x 190mm x 745mm

2. One time scaling ratio error: small and medium-sized particles ≤ 0.6%, large particles ≤ 2.0%.

3. One time sampling error: small and medium-sized particles ≤ 3%, large particles ≤ 4%.

4. One time sample reduction ratio: 1/2 (need to merge samples), 1/4

5. Sample boxed grain quality: 700g (based on wheat)

6. Maximum sample size: 2.8kg (based on wheat)

7. Minimum sample size: 200g

8. The sample does not need to be repeatedly mixed

9The maximum sample size is related to the size of the sample box, and replacing the sample box can achieve a larger one-time sample size
