Automatic motorized test probe for the PCE-5000 hardness tester with a test force of 8N. The PCE-5000-STAND test stand for the PCE-5000 hardness tester is used to support the automatic test probes. The test stand allows automated measurements, with a higher reproducibility of tubes and round material.
When leaving a mark or indentation is not an option, nondestructive ultrasonic technology can be used. Concrete rebound Schmidt hammer – is a device for concrete and other building materials strength testing. The most common in the world instrument for measuring the strength of concrete is the Schmidt Hammer. The device is called by the name of the engineer Ernst Schmidt, who invented the construction of the sclerometer.
Equotip 550 UCI Portable Hardness Tester
Dolphin-nose systems allow for the hardness testing of inner, as well as exterior, diameters. The systems are generally larger in size than other bench Rockwell systems, offering greater testing heights and depths. Dolphin-nose models offer a manual handle that activates the preload system or an advanced auto z-axis preload system. Using the auto z-axis preload system, after placing the workpiece in testing position, the operator only needs to press the start button for the machine to complete the testing process. Can test non-destructive and handle small or thin work parts down to 2mm of thickness, as well as testing large parts.
Leeb Hardness Tester NOVOTEST T-D2 uses dynamic method of hardness testing – Leeb method, standardized according to ASTM A596. SU-300H Manual Ultrasonic Hardness Tester is a classical portable durometer made by Sinowon group. It applies method of ultrasonic contact independence to make hardness testing at the spot or in the laboratory.
There are three types of turret control, including a basic manual turret for changing from optics to in-dentation and back to optics for measuring. A second type incorporates an automatic turret, giving operators greater freedom to change the turret position by a button on the tester keypad. The most popular Vickers/Knoop hardness testers have a turret-control option that uses software to control the entire test with a one-click process using calibrated auto-edge detection. Precision video and measurement software also allows for clicking of the indent edges in software and then deriving a hardness reading on screen.
Regardless of the Rockwell scale or indenter being used, the overall Rockwell test procedure is the same. The indenter is brought into contact with the material to be tested, and a preliminary force is applied to the indenter. vision measurement systems manufacturers is usually held constant for a set period , after which the depth of indentation is measured. After the measurement is made, an additional amount of force is applied at a set rate to increase the applied force to the total force level . The total force is held constant for a set time, after which the additional force is re-moved, returning to the preliminary force level. After holding the preliminary force constant for a set time, the depth of indentation is measured a second time, followed by the removal of the indenter from the test material.
However, the UCI method has the advantages of being nondestructive and able to test thin and small workpieces. They can also quickly convert that hardness value into HB, HV, HK and many other scales. Desirable hardness tester features include the ability to obtain ultraprecise results, a wide measuring range and scale/selectable test-force capabilities. In addition, automatic main test-force loading/unloading, a high-resolution digital display and USB data storage are all advantageous. Ultrasonic Hardness Tester UCI – 3000D is a combined portable Hardness tester integrated with the ultrasonic Hardness testing method and dynamic Leeb hardness testing resolution in one instrument. UCI – 3000D is an updated product based on Ultrasonic hardness tester UCI-3000, it includes all the functions of UCI-3000, and so it supports all of static Ultrasonic measuring probes and Leeb dynamic impact devices together.

They are then automatically converted to Rockwell C, B, Brinell, Vickers and Shore values. The portable benefit also means the tester can be brought to the workpiece, which is especially useful when testing large and/or cumbersome parts. This method has resulted in efficient, fast and accurate portable hardness testing results.
The UCI hardness test is a superficial determination, only measuring the hardness condition of the surface contacted. The results generated at a specific location do not represent the part at any other surface location and yield no information about the material at subsurface locations. ASTM International is providing no-cost public access to important ASTM standards used in the production and testing of personal protective equipment. When using an Ultra Sonic Hardness tester, always test the equipment first before the operation. Learning the equipment, even though they are relatively easy to use, will help ensure accurate testing results.
The ASTM D2674 standard specifies a method for determining the efficacy of an etchant used to prepare the surface of aluminum alloys for subsequent adhesive bonding. The specimen used for ASTM A1038 hardness test, generally consists of a probe containing a rod with a defined indenter. TheUCI-3000comes equipped with mass storage capabilities, simple calibration, a large LCD display, and quick measurement techniques that can be carried out in less than 2 seconds. Large LCD Display – Direct display measurement result, time count, maximum, minimal, average and deviation.
