Grain tester model 1938

Volume measuring device

Determination of the bulk of a liter of grain and conversion to EU bulk density for trade

  • Bulk density for barley, oats, rye and wheat.
  • Robust design (brass), 0.25 liters or 1.0 liters
  • Simple and easy operation
  • Exact measurements
  • Good reproduction

Usage area

The high-precision grain testers are used to measure the EU bulk density (bulk per hectoliter, hectoliter weight) of barley, oats, rye and wheat. The bulk is determined with the aid of a balance. The ratio of bulk to volume results in the bulk density, which is corrected with the factors from the »official tables« for liter and quarter liter samples. A calibrated balance is required for determination in the trade, and is available as an accessory.

Function

Insert the skimming knife, insert the forerunner into the measuring cylinder, fit the forward cylinder (1.25 liters) and pour in the grain sample. Pull out the skimming knife quickly. The forerunner and the grain fall into the measuring cylinder (1.0 liter). Cut the volume exactly using the skimming knife. Pour out excess grain, remove the forward cylinder and weigh the contents on a calibrated precision balance. The bulk density (kg/hl) of the different grain types is then determined on the basis of the provided correction table.
