Brinell hardness meter is measured with the 10mm steel balls and 3000kg load force, and the surface area of spherical indentation is larger, which makes the test results have a better overall representation, will not be impacted by the measured individual organizations of artifacts, the measured value has a high accuracy, and the errors are smaller.
The original Brinell hardness tester for the large laboratory equipment can not detect the field workpiece, the PHB-3000 hydraulic Brinell hardness Tester produced by Shenyang Tianxing is a portable hardness tester, with the weight of less than 14kg, which is simple to operate and easy to carry to the workshop for measuring large, assembled, difficult to move and non-slicing workpiece. The instrument is tested according to the real Brinell hardness test principle, the same as the principle of desktop in the lab. The calibration accuracy of test force is 0.5% of the load and the hardness test accuracy is the same as the desktop. What’s more, the instrument PHB-3000 can use a variety of test forces and select various ball indenters, which wider its test scope a lot. The range of measurement can reach 16~650HBW, which can meet most of common metal measurements of Brinell hardness requirements quite well.
