Gauge block test station EMP II

The innovative EMP II can test class 0, 1 and 2 gauge blocks. With a measuring range between 0.5 and 100mm and a resolution of 0.01µm, it is always precise.

For gauge block testing classes 0, 1 and 2:

  • 0 Gauge blocks to calibrate other gauges and measuring devices in an
    air-conditioned measuring laboratory
  • 1 Work standards in measuring chamber to check gauges and to adjust
    measuring devices
  • 2 Work standards in production process to check gauges and to adjust
    measuring devices

System description

Thermal influences on the measuring result are mostly reduced by setting the EMP 2 up locally consisting of a heavy cast base with positioning and measuring unit, a motor switching unit and PU 23 interface unit.

Comparison occurs against gauge blocks which are at least one class better. The extremely precise mechanics to position the measuring heads on the sample, guarantee a high degree of reproducibility of the measuring results and therefore fast and reliable calibration of your gauge blocks. Tests are carried out according to DIN EN 3650 and meet DAkkS requirements.

Optionally available measuring, documentation and
administration software automatically processes all measuring results of the PU23 interface unit and ensures a complete documentation of your gauge blocks.
