TeleBrineller
The TeleBrineller is a portable device capable of making hardness measurements of metals in the field. This method uses a tungsten carbide ball indenter and standard hardness bars. By comparing impressions made simultaneously on the standards and the sample, the hardness of an unknown can be determined with reasonable accuracy. This method is similar to a Brinell measurement in terms of the size of the indentation and the method of calculation.
