SPECIFICATIONS: The instrument consists of a channeled base over which two vertical pillars are fixed. An adjustable cross plate is at the top. A dial gauge, reading to.002mm x 12 mm. can be fixed to the top cross plate. The plunger end of the dial gauge can be located upon a 6.5mm. dia. ball or other reference cemented in the specimen. On the base there is a similar recessed seating in which can be placed a second ball or reference point in the specimen. Complete with a stainless steel standardization bar with insulated grip and with 6.5mm dia. balls mounted in the ends. The unit can be supplied with a .0001inch x 1/2inch dial gauge at extra cost if indicated at the time of placing the order.

This instrument is used for determining the time setting of hydraulic cement. Specification: A base with a vertical shaft and two horizontal arms. The lower arm is adjustable for height. 1 No.. Initial Needle 1/12 inch dia 1/4 lb.wt. 1No.. Final Needle 1/12 inch dia. 1lb.wt. 1 No. Glass base plate. Complete as above.

The apparatus is used for determining the fineness of cement in terms of specific surface expressed as total surface area in square centimeters per gram of cement.

SPECIFICATIONS: The mortar permeability apparatus comprises three brass/gun-metal cells mounted on a stand and a pressure chamber with a pressure regulator. The cell can accommodate 100 mm dia X 50 mm high specimen. Each cell assembly consists of one base plate. The base plate has one outlet for water and is recessed to hold the specimen in place with a ring washer in between. The top plate has an inlet for water and a suitable connector for the application of pressurized water in the cell. The mould and collar are clamped between the base plate and the top plate with the help of four tension rods and nuts. The cells are mounted on a stand. The pressure chamber is fitted with a pressure regulator which helps in regulating the pressure from 0-7kg/sq.cm.

SPECIFICATIONS: The machine consists of:- 1. A disc rotating at a speed of 30 rpm in a circular tray. 2. A bracket is provided to hold the specimen. 3. A counter balance lever loads the specimen. 4. Load applied is 30kgf. 5. A funnel is fitted to evenly spread abrasive powder on the grinding path. 6. A pre-set counter automatically stops the machine after 22 revolutions. 7. This counter is re-adjustable. 8. The machine works on 440 volts AC, three phase electrical supply. 9. On request machine to operate on 230Volts A.C. supply can also be supplied.

SPECIFICATIONS: The special features of pumping units is that the plungers of the pump have tolerances and no seals are used in the units and special type of non return valves as against traditional ball valves are used, which gives much longer trouble free service. Electrical Pumping Units work on 230Volts A.C. or 440 volts A.C.3 phase depending upon their capacity and these can be operated by hand in case of power failure. The front panel accommodate pressure gauge, on/off switch, slow fast lever to control the rate of loading and indicator lamps. Further in electrical units a micro switch fitted in the pressure gauge and a connected to a relay automatically cuts of the power supply to the unit when gauge capacity is reached. A dummy pointer to record maximum load applied is fitted on the cover glass. In hand operated pumping units, two plungers of different diameter are used. The plunger with larger diameter pumps oil at faster rage and is used for initial loading. Further load is easily applied by the second pump which has a smaller diameter plunger, The lever for operation of the pump is sufficiently long to minimize efforts and these units are suitable for site use.

SPECIFICATIONS: The Equipments comprises of a conical metal mould 1.5inch dia. at the top, 3.5 inch dia. at the base and 2.7/8 inch in height. A metal tamping rod weighing 12 ounces and having a flat circular tamping face 1 inch in diameter.

Specifications: The jolting apparatus consists of a rectangular table rigidly connected by two support arms to a spindle at a horizontal distance of 800mm from the center of the table. There is a projecting lug with a plane face on the ower face of the table beneath which is a stop with a rounded upper surface. The table can be raised and allowed to fall freely on the stop by a cam which is connected to a motor and gear box through a V-belt and pulleys. The cam rotates at a rate of 60 rev./min. A stroke counter fitted with micro-switch is provided which stop the machine after 60 jolts. Locating pins are provided for mounting the mould compartments on the table. The mould surmounted by the hopper can be clamped rigidly to the table. Supplied complete with mould and hopper. Suitable for operation on 230 Volts, single phase, A.C. supply. Spares and Accessories: (1) Steel mould with base plate having three compartments each having (2) Apparatus for demoulding the specimen.

DESCRIPTION: These are hydraulic jacks with integral pumping unit. The hydraulic pressure gauge is of 15cm dial on the side of hydraulic jack. A detachable lever is provided to operate the pump. Lift of the ram is 95 to 100mm. Face of the ram is flat. NOTE: Hydraulic jacks of 1000Kn & 5000KN capacity can be supplied with two speed pumping units. These jacks have lift of approximately 200mm.
