Portable Hardness Tester

Listing ID #1347101

We are Manufacturer and Supplier of Portable Hardness Tester D-2, which is an advanced Hardness Tester, distinguished by its high accuracy, wide measuring range, simplicity of operations and high portability. The Portable Hardness Tester is operating on three pencil cells of size AA. Our Portable Hardness Tester is suitable for testing the hardness of many materials & finds applications for hardness testing in many industries.
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 and latch arrangement. The motion of body is the measure of its kinetic energy. The instrument converts the signal of absorbed energy into a chosen scale of conventional hardness.
Applications :

• In-situ hardness testing of individual parts or components in assembled machine.
• Hardness testing of mould surface of a die.
• Hardness testing of heavy components, like rolls of rolling mill or Sugar or Paper industry.
• Hardness testing of heavy pressure vessels.
• Hardness testing of production line of components like crank shafts, cylinder blocks.
• Checking hardness of material in stock.
• Hardness testing when required in failure analysis.

• Display of hardness in various conventional scales of hardness as given in chart below for the standard probe.
• The instrument has compensation for the angle of probe with respect to vertical, while testing.
• Immediate conversion between available conventional scales of hardness.
• Standard deviation & average results up to nine readings can be taken.
• 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 to distinguish from batch to batch. The entire batch readings can be cleared or the batch number can be reset using the specific keys.
• The machine calibration can be done using the keyboard & there is no need of any expertise to recalibrate the machine.
• Serial port (RS 232) or printer port (Centronics Compatible) is available on request. At extra cost.

• Overall Dimensions of the Indicating Instrument : 150mm. long, 70mm. wide, 50mm. high approx.
• Weight Of The Instrument : 500 Grams approx.
• Operating Temperature : 15 degree to 45 degree centigrade approx.(Type Test report available)
• Measuring Accuracy : Mean uncertainty +/- 2.0 % (corresponding to +/- 1.6 HRC at 58 HRC) on standard test block. Or +/- 10 BHN on brinell test block.
• Operates on three dry pencil cells of size AA.
