     Description                                                                                               
   The Wallace H14 is a digital, bench-mounted hardness tester designed for measuring in IRHD the hardness of standard rubber samples. The robust, ‘C’ frame design allows the operator easy access from front and sides to safely load and remove samples. The indenter mounting is frictionless and its position sensed by an LVDT, providing the instrument with outstanding sensitivity. Adjustable anti-vibration feet reduce the effect of external vibration.

The robust, ‘C’ frame design allows the operator easy access from front and sides to safely load and remove samples. The indenter mounting is frictionless and its position sensed by an LVDT, providing the instrument with outstanding sensitivity. Adjustable anti-vibration feet reduce the effect of external vibration.
uBy 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.
uA range of optional sample tables is 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.
uRubber Hardness Test BlocksThe test blocks are for use as a check to ensure instruments are functioning properly and read correctly. They are not intended as standards with specific hardness values. Test blocks should be returned to Wallace every 12 months for re-calibration.
