Hardness Testers

The Digital Portable Hardness Tester is an advanced pocketable hardness tester distinguished by its high accuracy, wide measuring range, simplicity of operation & above all it is a really portable instrument operating on three pencil cells of size AA. It is suitable for testing the hardness of many materials & finds applications for hardness testing in many areas of industry.
Measuring Method:- The measuring principle is based on absorption of kinetic energy & its relation in
conventional scales of hardness. This is achieved with help of the probe, wherein a small body with a
hard tip is propelled against the test surface by a spring & latch arrangement. The motion of body is the  measure of its kinetic energy. The instrument converts the signal of absorbed energy in to a chosen scale of conventional hardness.
Typical applications for hardness testing with the portable hardness taster:-
1) In-situ hardness testing of individual parts or components in assembled machine.
2) Hardness testing of mould surface of a die.
3) Hardness testing of heavy components like rolls of rolling mill or sugar industry or paper industry.
4) Hardness testing of heavy pressure vessels.
5) Hardness testing of production line of components like crank shafts, cylinder blocks.
6) Checking hardness of material in stock.
7) Hardness testing when required in failure analysis.
Functions available on the display of Indicating Instrument of the portable hardness tester:-
1) Display of hardness in various conventional scales of hardness as given in chart below for the
standard probe.
2) The instrument has compensation for the angle of probe with respect to vertical while testing.
3) Immediate conversion between available conventional scales of hardness.
4) Standard deviation & average results up to nine readings can be taken.
5) The readings can be recorded & recalled for later viewing. The max capacity being 500 readings. The
readings are stored serially & the serial number being displayed. There is a batch number facility as
well to distinguish from batch to batch. The entire batch readings can be cleared or the batch
number can be reset using the specific keys.
6) The machine calibration can be done using the keyboard & there is no need of any expertise to
recalibrate the machine.
7) Serial port (RS 232) or printer port (Centronics Compatible) is available on request.

Model B - 3000(J) : Simplest model of Brinell Hardness tester with mechanical design, loading, unloading manual, best suitable for testing
batch quantities.

Model B - 3000(H) : Machine designed with a hydraulic power pack & control circuit for effortless loading unloading operation. A dial gauge
in front measures depth of ball penetration. This facilitates production testing within tolerance limits by compression method.

Model B - 3000(O) : Basic Machines design & operation similar to B-3000(H). In addition, an 'optical device' with 14x magnification provided
in front to project dia of ball impression on glass screen with a micrometer measuring system with 0.01 mm accuracy. The indenter swivels and
projects dia of ball impression immediately after unloading operation which avoids additional time for measurement of ball impression. This gives
real Brinell number on production testing.

Brinell Hardness Testers Model B-3000(H), (O) & (J) are precision engineered conforming to IS : 2281 - 1983, BS :240 and 240 and ASTM : E 10, however B-3000 (H), (O), (J) are most suitable for production testing.Â

These machines are designed to measure hardness of casting, forgings, other metals and alloys of all kinds, hard or soft, whether flat, round or irregular in shape.

Vickers Hardness Tester is simple & accurate in design. It is suitable for measuring the hardness of precision metallic parts with wide
testing range - from soft to hard & their accurate results are widely acclaimed. These testers strictly conform to IS "1754 Part I & Part
II – 1986
To accommodate the high precision loading system & an optical projection screen the machine frame
is designed sturdy. Specimen is placed on testing table. The test cycle is fully automatic. The accurate
load is applied on a diamond penetration by means of a lever & weights. The load is removed
automatically after a specific lapse of time. The objective is indexed with the test piece & the diamond indentation is projected on the measuring screen. The diagonals of the indentation can be measured by means of the micrometer screw of the projection screen.
