Hammer impact Brinell hardness tester applies test force by impact hammer and accurately controls the force by shear pins. It pressed the sample under the effect of hammering instantly. And the indentation of measured diameter can be converted into Brinell hardness value immediately. Our product is generally used to test large and medium-sized castings, forgings, steels, nonferrous metals as well as the semi-finished workpiece processed by quenching and tempering heat treatments, so hammer impact Brinell type is suitable for testing large forgings and castings with thick and big grains. Hammer Brinell hardness type’s testing range is from 100 to 350HBW when equipped with 7.26mm steel ball indenter while its testing range is from 350 to 650HBW when equipped with 4mm steel ball indenter. Compared with other impact types such as Shore type and Leeb type, Brinell hardness type’s result is influenced little by the outside factors, so its result is more stable and reliable. Additionally, Hammer Brinell type can leave a permanent Brinell hardness indentation which facilitates subsequent inspection and testing. In addition, Hammer Brinell hardness tester has a simple structure and cheap price and it is widely used in castings, forgings, rollings, heat treatments and other industries in China due to its simple structure and low price.

The SRBH-150 Portable Brinell HardnessTester is designed following the Brinell hardness test method. The test force is controlled by a shear pin. After reading the diameter of the indention with the reading microscope, the Brinell hardness value can be obtained from the lookup table. The SRBH-150 Portable Brinell Hardness Tester has two types of application: C clamp and hammer impact. It is capable of testing from small to very large specimens. It is especially suitable for assemblies inconvenient to be taken to the lab and not allowed to be cut. The test can be completed in any direction to test the hardness of upper, lower and lateral part of the specimen. The test head itself can be used as a hammer impact tester. It can perform the testing by touching one side of the work piece. Its accuracy is much higher than any other type hammer impact tester. According to the similarity principle of Brinell hardness testing, with testing force of 1580kg, indenter diameter of 7.26mm, then F/D2=30. The test condition of the HB tester is equivalent to the standard Brinell hardness test with 3000kgf and 10mm ball indenter. The SRBH-150 Portable Brinell Hardness Tester can be widely used to test the hardness of forgings, castings, steels, nonferrous metal and its alloy products, and to test the hardness of annealed, normalizing and tempered mechanical parts. 
Compared to the Leed type hardness tester, the Brinell tester has many advantages such as higher precision, fewer factors affecting accuracy and lower requirement on the surface roughness. The test result meets the requirements of most drawings without conversion and is more widely accepted in the international business.

SRBH-3000 portable Brinell hardness tester is the unique portable hardness tester in the world which applies test condition with 3000kg test force on a 10mm carbide indenter. It adopts hydraulic principle which functions the hand-operated way to apply 3000kg test force. The central part of SRBH-3000 is a small hydraulic system in which a release valve is used to control the test force. When the force reaches 3000kg, the release valve will open and the pressure will fall. As specified in the operation manual, the tester needed to be forced to make the indicator of the dial pointed at 3000kg test force for 3-5 times. Thus it is equivalent to the test condition of Brinell hardness testing method to hold 3000kg test force for 10 seconds with 10mm steel ball, which complies with ASTM E110.The large indentation resulted by the tester can reflect the average value of combined influence affected by all the compositions of large materials. It is unaffected by certain composition of materials or partial nonuniform distribution and very suitable for testing nonuniform materials made of large crystal particle. The testing result of this instrument is true and accurate with good repeatability and it has a good correspondence with tensile strength.

SRBH-3000a is a portable Brinell hardness tester has the same structure as PHB-3000 hardness tester, in fact it is another type of PHB-3000 with a chain. So It is also the portable hardness tester which applies test condition with 3000kg test force on a 10mm carbide indenter. It is consist of a test head and test frame. The test head is a mini hydraulic system which contains a control valve for controlling force. When force loading to 3,000Kgf, the control valve opens, pressure releasing. According to ASTM standard, force loading should be repeated 3 to 4 times, keeping the pin of the pressure gauge reaching the point of 3,000Kgf 3 to 4 times. In this way, it equals the test regulation of test force 3,000Kgf, 10mm test ball, force maintaining time 10 to 14 seconds.  The testing result of this instrument is true and accurate with good repeatability and it has a good correspondence with tensile strength. It is the best mechanical property tester can be used on site. The test condition and accuracy meets the requirements of ISO 6506 and ASTM E110. 
It can be used to test rough castings, forgings, nonferrous metals and semi-finished products after tempering heat treatment, On-site testing of Steel Pipe, Bearings, Gas Cylinder.

SRBH-750 Magnetic Hydraulic Brinell Hardness Tester is consist of 2 magnetic chucks and 1 hydraulic Brinell hardness test head, which is applied to test body hardness of huge iron and steel work pieces on site. The core part is a small hydraulic system. The operator could load 750kg test force by using the handle. There is a release valve to control the test force. When the force reaches 750kg, the release valve will open and close and then the pressure will fall down. According to ASTM E110, it is kept loading to make the indicator of the dial point at 750kg test force for 3-4 times altogether. Thus it is equivalent to the test condition of Brinell hardness testing method to hold test force for 10-15 seconds. The test condition of the hardness tester is 5 diameter test ball and 750kg test force, so the values of F/D2=30, of which the test result equals to the test condition of 10mm test ball and 3,000kg test force. The method complies with the regulation of ASTM E110. And the test accuracy complies with regulations of ASTM E10 and ISO 6506. 
It can only be applied in magnetic iron and steel work piece, not those non-magnetic nonferrous metal, high manganese steel, wear resisting cast iron and austenitic steel, etc.
It can be applied in testing flat surface work pieces and mono-diameter cylinder work piece with diameter larger than 150mm by specific customized cylinder adapters. If testing pipe materials, the thickness of the shell of pipes should be larger than 15 to 20mm, depending on different diameters. It could test steel plates, pipes, bars, moulds and huge castings, forgings, and heat treatment work pieces as long as the test area is big enough.
