Determination of the weight of 1000 grains

Applications :

Qualify your seeds.
Estimate the number of grains to be sowed to obtain the good density of sowing.
Estimate the agronomic yield, the flour and middlings extraction and the brewing yield.

Principle :

Can count all kind of items between 1 and 15 mm (grains, seeds, etc.) thanks to the single bowl and the adjustment screw which eliminates over-sized products from the count and prevents several items passing in front of the sensor together. Pre-selection of number of elements to be counted and automatic stop of bowl vibration when the selected number is reached.

Compliant with:

The Numigral complies with AFNOR NF V03-702 and ISO 720 standards for the determination of the weight of 1000 grains



A unique bowl suitable for all types of grains from 1 to 15 mm
