The Hildebrand Durometer Operating Stand Model OS-2 allows for accurate and repeatable Durometer readings. It rules out subjective test errors, which may be caused by differing load application forces or non-vertical application of the durometer to the test piece. Features: The Durometer Operating Stand works on the constant load principle. The sample is positioned on the support table. The durometer is lowered shock-free by means of a manually operated lever. The hardness value can be read directly from the Durometer. The stable Durometer-unit consists of Aluminium. Due to the low weight the durometer-unit can be easily adjusted in height. Small and big samples can be tested in the Durometer Operating Stand. A crash ring - mounted on the column - eliminates a crash between durometer and support table, when lifting or lowering the Durometer-unit.
