The Wallace H12 is a digital bench-mounted hardness tester that allows accurate and repeatable measurements in IRHD to ascertain the hardness of rubber samples. In particular it has been designed to accurately test thin sections and small test pieces such as O-rings.
The robust ‘C’ frame design allows the operator easy access from front and sides to safely load and remove samples. The indenter mounting is essentially frictionless and its position sensed by a linear variable differential transformer, providing the instrument with outstanding sensitivity. Adjustable anti-vibration feet reduce the effect of external vibration.
By simply pressing the start button, the instrument functions automatically, allowing accurate, repeatable results to be recorded in much less time than traditional models.
As minimal training is required, new operators soon become confident with the H12, achieving consistent readings from the outset.
A range of optional sample tables are available, designed to locate samples of varying shapes and special sample holding fixtures. It includes the O-ring adaptor (H19/ORA) that ensures the centre of the ring is directly beneath the centre line of the indenter.
