Notes:

When quoting a Brinell hardness number (BHN or more commonly HB), the conditions of the test used to obtain the number must be specified. The standard format for specifying tests can be seen in the example "HBW 10/3000". "HBW" means that a tungsten carbide (from the chemical symbol for tungsten or from the Swedish/German name for tungsten, "Wolfram") ball indenter was used, as opposed to "HBS", which means a hardened steel ball. The "10" is the ball diameter in millimeters. The "3000" is the force in kilograms force. Be advised to get the suitable instruments on simply send your inquiry to us

CV Instruments Premium Closed Loop Hardness Tester EW-150 Series (formerly Eseway Digital Micro Hardness Tester 420) ia high-end Vickers/Knoop/Brinell hardness testers with low and high forces ranging from HV0.02 to HV50. The EW-150 series features state of the art Closed Loop, Load Cell, and Force feedback technology for a reliable fast measurement procedure.

The innovative CV Instruments Premium Closed Loop Hardness Tester EW-150 Series characterizes the indentation hardness of materials through the scale of penetration of an indenter, loaded on a material test-piece. Conversion to either hardness scales and real-time statistics can also be done from its user friendly menu. When doing the hardness tests, the minimum distance between indentations and the distance from the indentation to the edge of the specimen must be taken into account to avoid interaction between the work-hardened regions and effects of the edge. These minimum distances are oftenly distinctive for ISO 6507-1 and ASTM E384 standards. Hence, to minimize the human error in testing, the programmable motorized feature along with connectivity via RS-232 will allow you to review or print those testing data precisely.

The EW-150 series features state of the art Closed Loop, Load Cell, and Force feedback technology for a reliable fast measurement procedure. This instrument provide you the accuracy and repeatability through Closed Loop, Load Cell and Force Feedback system within 4 selectable models to suit your needs and budget.  The versatile and reasonably priced tester is suitable for integrated test by fabricators in defense industry, tool-making, optics, petrology and mineral, aerospace engineering. This instrument is highly applicable to measure:

However, if you are looking for a basic Brinell tester, you might also want to consider CV instruments CV-4000LDB Hardness Tester.
