Optical Brinell Hardness Tester

sss make optical brinell hardness testing machine designed for measurement of steel and other ferrous material. These machines are also used for hardness measurement of non-ferrous material like brass, bronze, and aluminum.   basic machine design and operation similar to sss-b-3000(h). In an addition optical device with 14x magnification provided in front to project dia of ball impression on glass screen with a micrometer measuring system with 0.01mm accuracy. The indenter swivels and project dia of ball impression immediately after unloading operation which avoids additional time of measurement of ball impression. This give real brinell number on production testing within tolerance limits by compression method  features effortless loading and unloading operations reasonable price   dimensional accuracy and compact design.
