SI Instruments has released the United Tru Blue hardness-testing machine. It has a closed loop load control head. This means it is suitable for several hardness scales, including Rockwell, Brinell and Vickers. It has a direct readout on the display for each of these scales.
When set up for a series of hardness tests, the tester has a one-touch operation for shop floor users. Built-in memory provides an overview of the statistics of the measurements.
The closed-loop load control unit allows the measuring head to be used on a non-standard frame. This allows the user to measure parts that do not fit in conventional hardness testers.
