- Accurate & consistent results
- Easy access to sample area
- Operator dependency reduced
- Range of sample tables
- Four models offered
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 indentor mounting is frictionless and its position sensed by on LVDT providing the instrument with outsanding sensitivity. The 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 readings from the outset.
A range of optional sample tables is available, designed to locate samples of varying shapes and special holding fixtures.
Keys on the front panel easily adjust the measuring head up and down to suit the sample height.
Once the start key is pressed, the foot descends to secure the sample followed by the indentor, which lowers through the centre of the foot with a primary load of 0.3N to find its datum position. After 5 seconds, in line with the testing standards, the force is increased to 5.7N and applied for a further 30 seconds. At this pont the instrument identifies the indentor position and the hardness value is aujtomatically frozen and displayed clearly on the LCD screen. Two LEDs on the instrument's front panel monitor all stages of the test cycle.
