Wool measurement

Merino stud rams are mid-side sampled and the test results are displayed in the sale catalogues.

Here the core samples are cleaned, dried and prepared for measurement under strict test methods.

Crossbred and coarse wools are often measured for mean fibre diameter by older instruments—"Airflow" in many parts of the world, and even a projection microscope in some cases.
