AT350 Automatic Rockwell Tester

The AT-350 Automatic Rockwell Tester is a complete Rockwell testing system for testing in the factory, in the lab, and built into a fully automatic inline system. It provides complete automation of the Rockwell test cycle by press a start button - instead of pulling a lever.
  • A vital element for inline and automatic systems where dirt and vibration would upset the results of another automatic Rockwell tester
  • Tester has a small down-stroke to allow for a part to move into (and out of) position for inline systems
  • The test head removes for factory calibration/repairs
  • Operates according to ASTM E18

at300 electronics provide capability for control

AT300 automatic Rockwell tester is useful for using on inline applications

The electronics allow complete setup and control of the test cycle including time at load. Ernst Rockwell testers have been the main cause of success for a large number of working inline systems worldwide and especially in the USA.
