Indentec, the specialist hardness testing division of the Zwick Roell Group, has introduced a portable Rockwell hardness tester.
Unlike all other portable instruments the RH-150 performs a true Rockwell test in accordance with both ASTM E18 and ISO 6508-2 standards.
The device is ideal for testing thin metallic samples.
This is not possible with other portable units that use either the Leeb (rebound) or ultrasonic contact impedance (UCI) methods.
Samples up to 100mm thick can easily be tested.
Operators are prompted through the test cycle by simple instructions displayed on the LCD front panel.
Being powered by battery (60 hours continuous use, one-year shelf life) enables the RH-150 to be portable as there is no requirement for power cables or additional indicator units.
A load cell monitors and displays the applied force during the test cycle while a digital transducer measures the indentation depth and converts this to a Rockwell value with a resolution of 0.1 Rockwell point.
Rockwell HRA, HRB and HRC tests can be performed simply by fitting the correct indenter.
Various materials can be tested and results converted to Vickers, Brinell or UTS equivalent.
Up to 500 individual test results can be stored and transferred via an IrDA red transmitter to a printer.
In addition to the hardness result, the RH-150 also displays the average, maximum and minimum values.
Combined with an accuracy of +/- 0.5 Rockwell point at 60 HRC makes it ideal for quality inspection testing.
As with all Indentec products the RH-150 is supplied with comprehensive calibration certification.
A range of UKAS accredited test blocks are supplied, allowing regular verification checks.
