Hardness picks make hardness testing a more precise process - especially when testing small specimens or mineral grains within a rock. The point of the pick can easily be placed on the part of the specimen that you want to test. The scratches that you make or trails of metal that are left behind are usually very easy to distinguish. Simply hold the pick in your hand like a pencil and place it on the area that you would like to test. Then, with pressure, drag the point across the surface of the specimen. It will either leave a scratch, slide without scratching, or leave a trail of metal behind. The set includes eight points - for Mohs hardness of 2, 3, 4, 5, 6, 7, 8 and 9. The 2 is a plastic point, the 3 is a copper point, the others are alloys carefully selected to match the hardness of the Mohs index minerals. The set includes: • Four double ended picks with hardness points of 2-9 on Mohs hardness scale • A grinding plate for sharpening your points • Streak plate • Glass plate for quick \\\\\\\\\\\\\\\"hard\\\\\\\\\\\\\\\" or \\\\\\\\\\\\\\\"soft\\\\\\\\\\\\\\\" determination • A hardness plate with a hardness of 3.5 • Magnet • Paper table listing common minerals and their hardness • Hardness testing instructions

Ref. Standard : IS:10050 It is used for determination of resistance offered by rock to weathering and disintegration when subjected to immersion in water and has facility to test upto four seats of samples. Unconfined Compression Tester Ref. Standard : ASTM 2938 This equipment is used for determining unconfined compressive strength of intact rock core specimens. The rock sample is cut to length and the ends are machined flat. The specimen is placed in a loading frame and if required heated to the desired test temperature. Axial load is continuously increased on the specimen until peak load and failure are obtained

• Heavy duty, pillar type frame with 1500W, single phase, AC motor • Varying cutting feeds provided with water-fed swivel head which can be connected to suitable water supply. • Provision at base for water collection / drainage Core preparation from regular and irregular samples Core size : EX to 100 mm • Clamping arrangement to hold specimens with regular/ irregular shapes to the base of machine • Two cutting speeds at no load 950/2100RPM. • Water tank 5ltr. is Standard outfit

This unit is designed for cutting and grinding cylindrical rock specimens upto NX size. The outfit includes 200 mm dia diamond impregnated cutter, a fine diamond impregnated grinding wheel, a water supply system and sample holder. A V-Vice, to hold the sample upto 55 mm dia x 140 mm long to be cut parallel and square to the longitudinal axis is provided. Cores longer than 140 mm can be prepared by reversing the specimen and holding the same vice. A hand feed arrangement is provided to facilitate the specimen with a uniform and smooth feeding motion. Suitable for operation on 415 V, three phase, AC supply

Point Load Index Tester, is used for determining the Diametral Point Load Strength Index of rock cores and irregular lumps which can be tested without any treatment. The Point Load Test is primarily an Index Test for strength classification of rock materials. This instrument is mainly intended for field measurements on rock specimen but it can also be used in the laboratory. The results of the test may also be used to predict the uniaxial compressive strength of rock from correlations. The apparatus is light and portable. It can be used in the laboratory as well as in the field. Salient Features: • Rock core specimens can be tested without any preparation. • The results of the test may also be used to predict the uniaxial compressive strength of rock. • With this instrument, a wide range of core sizes can be tested. • The frame has adequate adjustments to align perfectly the loading axis passing through the centre of the bearing plates and loading

Triaxial cells are designed to withstand a lateral pressure of 150 bar (150 kg/cm2). Four no-volume change valves are fitted to the base for measurement of pore pressure, top drainage, bottom drainage and for entry/exit of cell pressure. The cell is nickel plated and completely

Miniature High Pressure Permeameter determins the permeability characteristics of solidified soils and rock cores

Ref. Standard: IS-10070 This machine is for determining the resistance to wear off small size coarse aggregates and crushed rock. The machine consists of a hollow cylinder, mounted on a sturdy frame on ball bearings. A detachable shelf which extends throughout the inside length of the drum catches the abrasive charge and does not allow it to fall on the cover. The drum is rotated at a speed of 30-33 rpm by an electric motor through a heavy duty reduction gear. Supplied complete with a tray for collection of the material. Ref. Standard of the machine is as per IS:10070 Suitable for operation on 415V, 3 phase, 50Hz,AC Supply

Cylindrical Metal Measures, with ISI Certification Mark, IS:2386 (Part-3) Cylindrical Metal Measures with ISI Certification Mark, IS:2386 (Part 3) Consists of one each of the following measures: AIM 45401 Measure 3 litres AIM 45402 Measure 15 litres AIM 45403 Measure 30 litres Supplied Complete with AIM 345 Tamping Rod of 16mm dia x 60 cm long having ISI Certification Mark IS:10086

It is for determining the aggregate impact value and has been designed in accordance with IS:2386 (Part 4), IS:9377.
