Multifunction High Accuracy Digital Brinell Durometros (SHB- 3000C )

SHB-3000C is a half automatic and intelligent Brinell hardness testing machine, it adopts the load cell to replace the traditional quality weight, this innovative design makes the instrument more accurate.

SHB-3000C selection of testing force and dwell time is controlled and monitored on the front panel, it is automatic during the process of loading, dwell and unloading.

SHB-3000C adopts digital Brinell microscopes with adjustable LED illuminator, it doesn't need the operator to read the detail length of indentation, it only needs operator to aim the D1, D2 diagonal of indentation and press the length key twice above the Microscope, then the built-in computer can computer the Brinell scale and display the final testing result on LCD display automatically.

SHB-3000C supports the hardness conversion, it can use Brinell scale to get conversion scale of HRC, HRB, HRC, HV, etc.

The Brinell hardness test method consists of indenting the test material with a 10 mm diameter hardened 
carbide ball subjected to a load of 3000 kg. For softer materials the load can be reduced to 1500 kg or 
500 kg to avoid excessive indentation. 

The full load is normally applied for 10 to 15 seconds in the case of iron and steel and for at least 30 
seconds in the case of other metals. The diameter of the indentation left in the test material is measured 
with a low powered microscope. The Brinell harness number is calculated by dividing the load applied by
the surface area of the indentation.
