Rubber Hardness Tester Vtech made a vertical plunger. The lower side of the plunger has an indenter. The lower shape of the indenter is ball type of specified dimension. The upper sides of the plunger have a good eclectic conductive tip. The weight of the plunger and fitting attached to it is a minor force. A big brass weight is the major force of the specified weight. A dial gauge is attached to the instrument for the measurement of the penetration depth of the indenter to the rubber. An electricity operated buzzer, for gently vibrating the apparatus to overcome the slight friction is mounted under the cover of the instrument. The tester is finished in NC based painting and bright chrome plating to give it a corrosion resistance finish.

Max stroke: 200mm

Diameter of pressure needle: 1.25mm +/-0.15mm

    Direct reading Specific Digital Gravity Balance provides a simple and quick mean to read directly the specific gravity of rubber and other elastomers. Thus reducing labour and eliminating calculations. The time taken to find out specific gravity of a sample is only about half a minute. The balance consists of a rigid scale with a specific gravity (SG) printed on standing vertically on a heavy base plate. To the centre point at the scale, through jewel bearings to minimize the friction, a balancing arm is pivoted. At one end of the arm, two stainless steel pins are hanging with yarns. One of the pins is attached to glass jar kept on the base. A guard is provided to avoid accidental falling of the jar during use. At the other and of the balancing arm a pointer is fixed which indicates the specific gravity of materials under test. A sliding weight is also provided for initial balancing of the sample of different weight a levelling of the base plate. Two models of balance, one with a range of specific gravity between 0.9 to 3.0'' the second with a range of specific gravity / between 0.2to2.0 are available. A sample of any shape weighing between 5 and 12g can be tested in the first model, that weighing between 3 and 5g can be tested in the second model, and that weighing between 1and 2g can be tested in the third made. In the case of the second and third model, the lower pin is quite heavy and also acts as a sinker. Also in these models, the glass jar is kept on the base of a frame, which can be slid up and down on a rod fixed to the base plate to cover the full range at specific gravity

    De Mattia Flex Tester has a set of grips to hold test specimens in two tiers with their holding faces lying in the same vertical plane. Holding one end of the test specimen in a fixed grip and the other end in a reciprocating grip provides the flexing and unflexing action. The set of grip has two fixed grips and one large reciprocating grip positioned between them in order to flex half of the test specimen while the other half is being unflexed. The reciprocating grip is slide on hardened and ground rods made of high carbon steel. The reciprocating motion is provided by an eccentric and linkage mechanism driven by an electric motor through V-belt and pulleys. A six digit electronic counter is provided for indicating the number of the test cycles undergone. The equipment is built on a rigid fabricated base plate and finished in metallic painting and bright chrome/zinc plating to give it a corrosion resistant finish. Molding dies for preparing test specimen, and jig and punch assembly for making an initial crack in test specimen for crack growth test are available as optional accessories

    Technical Specification:

    Number of test specimens tested: Six (or Twelve)

    Maximum opening between grips: 75mm (adjustable)

    Travel of reciprocating grip: 57.15mm (adjustable)

    Flexing frequency: 300cpm

    Motor: 1/2 HP single phase 230 V AC
