The Unified Solution

Brinell® Hardness Testing (BHT)

Our inspectors use ultrasonic and eddy current flaw detectors that offer an unmatched capability for applications ranging from weld inspections to the detection of hidden cracks, voids, porosity and other internal irregularities in metals, composites, plastics and ceramics. Our high-quality flaw detection services offer numerous practical measurement features, application-specific software, ease-of-use, versatility, and ruggedness.

Analog Telebrineller hardness measurements are a direct comparison to a known physical reference and therefore, measurements are not subject to inaccuracies due to; alloy, thickness, geometry, position, etc., that are common with many other portable testers. The test bars which are the core of this system, are calibrated to a uniform hardness of ± 3% of the labeled BHN. Hardness of the bars is measured by equipment whose accuracy is certified traceable to the National Standards Institute. The Leica Telebrineller microscope readings may be made within .05 millimeters. The method consists of one hammer blow, and measurement of the resulting impressions and the manipulation of a basic equation are calculated on the computer.
Our Digital Brinell Hardness tester makes a Brinell impression in conformance with the standard method for Brinell testing. The resulting impression may be measured optically to determine the Brinell number. By utilizing a digital hardness tester, we can measure the depth of an impression. The depth of measurement method means faster testing, more consistent results, and less operator influence than traditional optical measurements allowing Versa to minimize human error and maximize uptime.
