Portable metal hardness testers vs. SHAAB D1

Leeb is one of the most common hardness testing methods that is used by portable testers and that has turned into a standard for itself. ASTM A956 and DIN 50156 Standards are used to measure the hardness value in Leeb method. Most portable hardness testers produced by leading companies in this industry use the same method.

In the Leeb rebound hardness test, the impact body, on top of which there is a hard and usually spherical object, is propelled by an impact device towards and then rebounds off the metal surface. The hardness value is proportionate to the velocity of the impact body as it travels toward and away from the surface of the workpiece.

SHAAB D1 Hardness Tester

SHAAB D1 Hardness Tester is a portable device which could be used for a vast range of metals in different industries. The small dimensions and the light weight of the tester have made it possible for the user to do the measurement while holding the instrument with one hand. SHAAB D1 hardness tester is the result of 20 years of experience in manufacturing various types of high-tech digital and electronic hardness testers.

This hardness tester measures the hardness value of metals using the Leeb rebound test method. The device can convert the Leeb number into other hardness scales such as Brinell (HB), Vickers (HV), Rockwell C (HRC-C) and Rockwell B (HRB-B). The measurement and the calculations are done in less than one second. The device saves the minimum, maximum and average hardness values for 9 consecutive tests. The tester is equipped with an LCD display and rechargeable Li-Polymer batteries and is calibrated by the standard reference block which is provided as an accessory of the device itself.

Applications

·         Measuring the hardness value of different metals in different shapes

·         Measuring the hardness value of metals which are too heavy and bulky to move

·         Measuring the hardness value of metal parts of large-scale machinery

·         Measuring the hardness value of metal pipes and CNG capsules

·         Measuring the hardness value of metals in small spaces, in production lines and during different stages of the production process

·         Non-destructive testing (NDT) where only a slight trace of hardness test will remain on the surface

·         Measuring the hardness value of metals while ???

·         Measuring the hardness value of welding links ???

·         Measuring the hardness value of architectural structures

Features

·         Shaab Hardness Tester facilitates easy measurement with no need for complex adjustments.

·         The device could be used for hardness measurement at different angles and directions.

·         It is applicable for hardness measurement of a wide range of metals including cast steel, Cold Work Tool Steel, ductile cast iron, grey cast iron, aluminium, brass, and copper.

·         The device can display the hardness value in all common hardness scales such as HB, HV, HLD, HRC, HRB

·         The user can convert the measured hardness value into other hardness scales using the device’s keyboard and conversion tables.

·         Shaab Hardness Tester is available in two models:

- one with a 2.5-g impact body suitable for measuring the hardness value of thicker and heavier metal objects with less even surfaces

- the other with a 1.5-g impact body suitable for measuring the hardness value of lighter and thinner metal objects such as CNG capsule with a minimum thickness of 6 mm where more superficial measurement is needed

·         The impact body could be removed in cases where the device dimensions make the measurement difficult or impossible.

·         The user can calibrate the device by himself using the reference test block.

·         The device can instantly display the hardness value measured as well as the average value in different measurement tests.

·         It can also display the minimum and maximum hardness values measured in different tests.

·         Shaab Hardness Tester is small and light and is covered by a rugged polycarbonate case.

·         The device performance and functionality are not affected by magnetic fields.

·         It enjoys an automatic power-off system to optimise battery usage.
