Chondrometer

A chondrometer is a measuring instrument designed to determine the bulk density of grain.

[1] Density is a guide to wheat quality and determines the price and the space required to store and transport the crop.

[2] A chondrometer consists of a filling hopper, a measuring container, a straightedge, a weighing instrument.

[1] The measuring cylinder has flat top edge to it can levelled using the straightedge (a strickle) to give a set volume.

Today, the measuring instrument can be a set of digital scales with an accuracy greater than 0.1 g, though in the past it was a steelyard balance with the measuring cylinder hooking directly onto the scales.
