“....linear digital measuring systems from fractions to 10 microns....”



ProTable-TUBE is a linear measuring system for measuring tubes, shafts, and rounds.  It is designed for use on a factory floor, and can be used for measuring wood, plastic, metal, ceramics, glass, and more.

ProTable-TUBE can be configured for different size ranges, product diameters, and product features/geometry.  The system is built on a sturdy aluminum plate, with precision machined parts, a recirculating ball bearing system, and nickel-plated, ground tool-steel contacts.

ProTables are built using quality aluminum extrusion and steel bearings to insure smooth operation and to minimize orthogonal, Abbé, and cosine errors.



  • Large Character, battery powered Digital Readout travels with the moving carriage.

  • Battery Operation: One CR123 Lithium battery in the Readout will power a ProTable for up to 12 months.

  • Non-Linear error correction: The ProTable Readout stores up to 126 calibration points along the measuring length for non-linear measurement compensation.

  • Automatic Temperature compensation: The Readout samples ambient temperature every 15 minutes and applies applicable correction to the measurement.

  • SPC Output: Measurement data can be sent wirelessly to a PC.

  • Easy Operation: Readout settings for Zero, Plus & Minus Offsets, Data Send, and Measurement Units.

  • Choice of Measurement Units: The Readout will display measurements in inches to .001 or .0005; Millimeters to .01; or Centimeters to .01.
