Grain Composition Sand Ruler is a handy field aid that allows you to determine the granular composition of sand samples you are collecting. An important quality of material in a soil profile is the grain size distribution or texture. Made from a robust transparent disc, which contains 10 fractions of reference material according to the sand median. A hollow in the centre lets users place their sediment sample so you can easily cross-reference it with the fractions to determine various factors of the material. Such as grain size, distribution, and more.

A handy field aid that allows you to determine the granular composition of sand samples you are collecting. An important quality of material in a soil profile is the grain size distribution or texture. One determines the soil properties by the texture of the soil. Such as the ease of tillage, the capillary conductivity of the soil, the available moisture, the permeability of the soil, compaction, rooting possibility, and more.
A grain-composition sand ruler is a disc of transparent, robust plastic. Within it, are 10 fractions that contain grain samples, increasing in grain size. A circular depression in the middle of the device allows you to place your sample material within it. Further allows users to easily compare their own sediment sample composition with the reference around the edges.
Using the sand median, it is possible to classify the sand fraction. A representative proportion of the sample you are testing is rubbed dry with the fingers in the palm of the hand. Then place the sample sediment in the hollow area in the center of the ruler. Users can now analyse the average grain size by comparing the average grain size of the sample with the specimen in the ruler.
The grain composition sand ruler comprises 10 fractions of reference material. They depict the following particle sizes: 63, 90, 125, 180, 250, 355, 500, 710, 1000, 1400, 2000 µm (micrometers).
