    Features Vickers Hardness Testers Model BV-250, BV-250-S, BV-120, BV -120 -S, BV -50, BV -50-S are suitable for Vickers and Brinell Hardness of steel and other metals. These machines are designed and manufactured for very high accuracy, reliability and ease of operation. The selection of load is effected with the push button control system. The measurements of diagonal / diameter of indentation is done with the help of built-in optical system with graduated readout with Micrometer. After taking indentation on the work piece, the objective lens is automatically swivelled into position and image of indentation appears on the focusing screen fitted in front of the machine. A push button is provided for starting the laoding cycle and unloading is accomplished through hand lever. This machine conforms to IS 1754 -2002 for Vickers and IS 2281 -2005, BS-240 for Brinell Test. Vickers Hardness Testing Machine BV-50 : Only for Vickers test load range 5 kgf to 50 kgf BV-5O-S : Only for Vickers test load range 1 kgf to 50 kgf BV-120 : Only for Vickers test load range 5 kgf to 120 kgf BV-120-S : Only for Vickers test load range 1 kgf to 120 kgf Vickers cum Brinell hardness Testing MachineBV -250 : For Vickers and Brinell Test load range 5 kgf to 250 kgf BV -250-S : For.Vickers and Brinell Test load range 1 kgf to 250 kgf Salient features 1. Testing range is very wide, from soft metal such as lead up to the hardest, like hardened steel. 2. Thin sheet metal is perfectly tested because the load applied is very small. 3. Same hardness number is obtained on the some specimen, regardless of the load applied. 4. Built in projection screen to get accurate results. 

. Brinell MicroscopeWe offer a compact and versatile instrument for linear measurement which has a pre-focussed objective and is therefore, suitable only for flat objects. The measurements are directly read on glass scale incorporated in the eye piece. The reticle is calibrated in 0.1 mm units over a range of 7 mm and the diameter of microscope field is 8mm. This microscope has a magnification of 25x which allows the user to measure the diameters of indentations made by the ball indenters of all brinell type hardness testing machines. This microscope is also easily used as a calibrated portable microscope and is supplied with 7w-220v lighting attachment.2.

FEATURES: The hammer type  Poldi impact Hardness Tester is suitable for measuring the Brinell Hardness of Steel ,Cast iron , Brass Aluminium. Copper etc. This Poldi Hardness Tester is useful to test parts where bench type model is not useful. This type of machine is most ideal and simple for foundries, Workshops , Engineering Colleges, Technical Institutions etc.  PRINCIPLE Load is applied by a hammer blow on the specimen and a standard test bar in linear direction through a hardened steel ball of 10 mm dia. The impact load on both is the same . The extent of indentation on the specimen and the test bar depends on their hardness. The two diameters of indentations on test bar and specimen are measured by a magnifier supplied alongwith the tester. The hardness of the specimen can be determined, by referring got the chart supplied with the machine. TECHNICAL DATA:Hardened Steel Ball:-10 mm dia , fixed in a special holder with a spring loaded plunger.Standard Test Bar:Each bar  individually calibrated and Multiplying Factor marked thereon.Magnifier:-Measuring range                         10 mm Scale graduation                         0.1 mmMagnification                                10xAccuracy of measurement         0.05 mmHardness Tables:-Comparison tables for finding hardness Separate Tables for Steel, Cast iron , BrassCopper and Aluminium.

Measuring Principle  Dynamic Hardness Tester is an extremely light weight, portable, fast & reliable hardness tester based on a novel, dynamic & Rapid test procedure with widest measuring ranges for metals. A carbide tipped shuttle with a definite kinetic energy is impacted on the specimen. A part of this energy absorbed by the specimen and is a function of the hardness of the specimen. A tubular device housing electrodynamic energy measuring device carries out the impacting of the shuttle. A measuring instrument receives the signal, equivalent to absorbed energy through a cable and displays with instant calculations. This displays Dynamic hardness (D) a three digit figure, which is proportional to the hardness of the specimen. The machine has built inconversion facility for given material to convert ‘D’ value to Vickers, Rockwell, Brinell scales which can be selected by pressing ▲▼keys. Application• In stores for Material identification. • Measurement of Hardness in confined spaces. • Variation in hardness over large work piece. • Large & heavy components. • Permanently installed parts. • Surface hardened component or hardness on coatings.
