Wallace-MRPRA Fatigue Tester The Wallace MRPRA Fatigue Tester measures the tensile fatigue resistance of rubber samples prepared in the form of standard Schopper rings.

Using wires of known stiffness, this instrument determines the torsional modulus of vulcanized rubber samples at low temperature, consisting of a measuring unit and a separate controller.

The top of each torsion wire is attached to a head while the bottom is fastened to a pointer and a coupling to which each sample is clamped. The deflection of the torsion wire is easily read from a protractor, marked in 1O divisions.

Three catridges are supplied with the apparatus, having torsional constants of 0.70, 2.81, and 11.24 mNm/rad of twist respectively. Each torsion wire is mounted in an easily removable stainless steel cartridge, attached to the torsion head by a knurled screw for finger tightening.

A revolving 10 station test piece rack is mounted on the measuring head support so that each test piece may be indexed accurately under the torsion wire.

The bath consists of a removable stainless steel container located in an insulated box to which the heater/stirrer unit is attached by thumb screws.

The controller houses the speed control for the stirrer motor and a digital temperature controller which displays the fluid temperature and the ramp rate of heater.

• Tests soft and hard materials using different Shore scales
• One touch, fully automatic operation
• Accurate & consistent results
• Easy access to sample area
• Operator dependency reduced
• Range of sample tables
• Four versions offered for each model

The Wallace range of H17 digital, bench mounted hardness testers, is designed for measuring in Shore scale the hardness of various materials. Four models are offered - the H17A for testing standard rubber, H170 for soft rubber and medium density textiles, H17D for hard rubbers and plastics and H17M for thin/small rubber samples.

The robust, "C" frame design allows the operator easy access from front and sides to safely load and remove samples. The adjustable antivibration 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 H17, achieving consistent readings from the outset.

A range of optional sample tables is available, designed to locate samples of varying shapes, sizes 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. In line with the testing standards, once the foot contacts the sample the indentation depth is recorded after a pre-set dwell time, typically 3 seconds. At this point the instrument identifies the indentor position and the hardness value is automatically frozen and displayed clearly on the LCD screen.

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.

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.
