We offer Specific Gravity Balance. Our direct reading Specific 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 specific gravity (SG) printed on standing vertically on a heavy base plate. To the center 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 pin is attached with 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 leveling of the base plate.

Two models of balance, one with range of specific gravity between 0.9 to 3.0’’ the second with range of specific gravity / between 0.2 to 2.0 are available. A sample of any shape weighing between 5 and 12g can be tested in the first modal, 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 case of second and third model, the lower pin is quite heavy and also acts as sinker. Also in these models the glass jar is kept on the base of a frame, which can be slided up and down on a rod fixed to the base plate to cover the full range at specific gravity.

Din Abrasion Tester is designed to determine abrasion resistance index of natural and synthetic rubber in accordance with the above principle. It consists of test specimen holder with a cylindrical opening adjustable between 15.5 to 16.3 mm to clamp the test specimen with an arrangement to adjust the length of test specimen protruding out. The holder is mounted by a screw mechanism along a length of a rotating drum on which the abrasive cloth is fixed. The movement to the screw mechanism and drum is given by an electric motor, gearbox and chain mechanism to give the specified speed of rotation to the drum and the specified lateral movement to the test specimen holder. The swivel arm and test specimen holder are so disposed that the test specimen is pressed against the drum under the specified load with its center axis at an inclination of 3 degree to the perpendicular in the direction of rotation and placed above the longitudinal axis of drum.

A rack and pinion arrangement to rotate the test specimen about its axis during the test (whenever desired) is also provided.
The abrasive cloth is firmly fixed to the drum using a suitable peel able adhesive with the ends of the abrasive cloth butt jointed together. The equipment is provided with limit switches which, in addition of giving over travel safety to the movement of test holder by preventing the lower edge of the test specimen holder to touch the abrasive cloth. The equipment is built on rigid steel base and finished in grey metallic and bright chrome / zinc plating to give it a corrosion resistant finish. Moulding die, rotary type cutting die (hollow drill) for preparing test specimens and extra abrasive cloth are available as optional accessories.

• IRHD type Tester 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 the 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.

Oxygen Index Apparatus consists of a test chimney made of borosilicate glass suppurated by the metallic base and hook with the help of the metallic pillar. The mixture of nitrogen and oxygen is released from the bottom of tube. The tube is filled with glass beads for mixing and evenly distributing the gas mixture. The specimen holder, which holds the test specimen, made of U shape and fixed at the center of the chimney. There is the porous screen mounted below the level of the specimen holder, to prevent falling combustion debris from fouling the gas entry and distribution paths. There is a digital temperature indicator cum controller with thermocouple for the measurement. A copper tube with suitable orifice for pilot flame is provided for igniting the specimen by inserting it from the top of the test column. The digital preset timer and buzzer is also mount in the instrument.

Two rotameter with needle valve are provided to control and measure oxygen and nitrogen flow in the test chimney. A timer for indicating the time of burning with a reset switch. The rotameter, temperature controller, timer are fitted in the sheet panel. The test chimney is fitted separately on the metallic platform. Gases, gas cylinders and its fittings are not provided with the equipment and have to be arranged by the purchaser.

Smoke Density Chamber is constructed using 14 gage aluminum box, which is hinged a heat resistant glass glazed door. This box is mounted on the base which houses the controls. Dependent upon the materials tested, the metal may require protection from corrosion. The chamber is sealed except for 25 by 30mm (1by 9in.) openings on the four sides of the bottom of the chamber. A liters/min specified capacity blower is mounted on one side of the chamber. The inlet duct to the bowler is equipped with a close fitting damper. The outlet of the bowler will be connected through a duct to the laboratory exhaust system. The two sides adjacent to the door are fitted with 70mm (2/3in) diameter smoke tight glazed areas entered 480mm (19/4 in.) above the base. At these locations and out side the chamber, boxes containing the optical equipment and additional controls are attached. A removable white plastic plate is attached to the back of the chamber. There is a clear area centered above the bottom of the chamber. Through which is seen an illuminated white on red exit sign.

The white back ground permits observations of the flame, smoke, and burning characteristics of the materials. The viewing of the exit sign helps to correlate visibility and measured values. The specimen holder is supported on a square gage. Stainless steel wire cloth above the base and equidistant from all sides of the chamber. This screen is lying in a stainless steel bezel supported by a rod through the right side of the chamber. From the same rod similar bezel is located below and it is support a square of asbestos paper which catches any particles that may drip from the specimen during the test. By rotating the specimen holder rod, the burning specimen can be quenched in a shallow pan of water positioned below the specimen holder.

The specimen is ignited by a propane flame from a burner operating at a specified pressure. The fuel is mixed with air which has been propelled through the burner by the venturi effect of the propane as it passes from small orifice. The burner is designed to provide adequate outside air. the burner is capable of being positioned quickly under the specimen so that the exit of the burner falls on a line passing through a point 8mm above the base at one corner of the chamber extending diagonally across the chamber and sloping up wards at 45 deg with the base.
