Set of support ring for Leeb Hardness Test

Established as a Sole Proprietorship firm in the year 2015 at Rajkot (Gujarat, India), we “Dhara Agency” are a leading manufacturer and Wholesale Trader of a wide range of Metallurgical Microscope, UTM And Impact Testing Machines, Surface Roughness Tester, Ultrasonic Thickness Gauge, etc.

Webster Hardness Tester is a portable instrument which can be used for on-site testing of aluminum alloys, aluminum profiles, tubes, sheets and other soft metals like copper and brass. The operating principle is simple. The specimen to be tested is placed between the anvil and the indenter Pressure is applied to the handles until “bottom” is felt and at this time the dial indicator is read. It is according to ASTM B647 standard.
 
Features:
Fast convenient and reliable instrument.
Single hand operation.
Indenter is made of a special material of high hardness having a long life and can be easily interchangeable whenever required.
The handle is made of forged aluminum alloys with fine anodized finishing.
Standard hardness tester model ‘W-20’ can test material from 0.6 to 6 mm thickness and inner die.(Ø) ≥10 mm.

Disadvantages are obvious for the hardness measurement commonly used like Brinell, Rockwell, Vickers, Leeb, etc. Rockwell and Brinell with heavy loading force and big indentation, lead to serious destruction on sample surface. Vickers apply optical measurement, but only professional technicians can operate smoothly, impossible to measure hardness of heavy work piece, installed machinery and permanently assembled parts. Leeb hardness tester apply rebound and indirect method to measure hardness, easily lead to big deviation when convert to Brinell, Rockwell and Vickers scales.

Ultrasonic hardness tester UHT-900 applies ultrasonic contact impedance method to do comparative hardness measurement for testing pieces, with advantages of high accuracy, efficiency, portable and easy operation.
Ultrasonic hardness tester UHT-900 is widely used to measure hardness of small forgings, cast material, weld inspection, heat affected zone, Ion-nitride stamping dies and molds, forms, presses, thin walled parts, bearings, tooth flanks, etc. 

SU-400 Dynasonic Hardness Tester is a universal portable durometerwith twin—testing-method. It applies twin-method aboutstate ultrasonic contact independence: UCI and dynamic rebound: Leeb to make hardness testing in one instrument, it solves the dilemma that Leeb method can not test the hardness of plating and coating(in UCI), and UCI method can not test the coarse crystal material in the casting industry(in Leeb).

SU-400 can not only work with the UCI motorized and manual probes, but also work with the Leeb impact probe, it is universal to test the hardness of material with the fine crystalstructure or coarse crystal structure in the metal industry.

SU-400 UCI probe system is perfect to measure hardness testing about the coating and plating, which can measure the hardness of chrome, copper plating, carburized layer and Nitriding layer effectively.

SU-400 dynamic Leeb probe system is suitable to measure hardness of coarse material, such as, casting and forging 

SU-400 is a NDT durometer due to the contact indention is too small to observe, it is one of the excellent solution to test hardness of finished products, such as, the mold, gear, shaft, rod, screw, rails, etc. 

SU-400 conforms the standard ASTM A1038-2005, DIN standard DIN50159-1-2008 and China National standard GB/T 34205-2017, GB/T 17394.

Product Details:
The hammer type Poldi Hardness Tester is suitable for measuring the Brinell Hardness of Steel, Cast iron, Brass Aluminum, Copper etc. This Poldi Hardness Tester is used to test parts where bench type model is not useful. This type of machine is most ideal and simple for foundries, Workshops, Engineering Colleges, Technical Institutions etc.

Principle:

The load is applied by a hammer blow on the specimen and a standard test bar in a linear direction through a hardened steel ball of 10 mm dia.

The impact load on both is the same.

The extent of indentation on the specimen and the test bar depends on their hardness.

The two diameters of indentations on test bar and specimen are measured by a magnifier supplied along with the tester.

The hardness of the specimen can be determined, by referring got the chart supplied with the machine.

Manufactured in accordance with AFS specifications, our Mould Hardness Tester is used to determine surface hardness of green sand mould. The Hardness test can be performed within seconds; user simply presses the tester against the mold surface and notes reading on the dial. Excessive pressure will not alter the reading and it operates in any position.

Details:

A 1/2 in. (12.7 mm) radius ball contact point is loaded with a spring pressure of 980 g. The softer the mold surface, the greater the penetration into the mold.

A mold offering no resistance to the contact point would have a zero reading and one having hardness capable of preventing penetration would read 100.

A maximum reading stop holds the reading when testing in blind portions of the mold
