DeFelsko PosiTector RTR 3D Replica Tape Reader

DeFelsko PosiTector RTR-3D Replica Tape Reader measures and records surface profile parameters using replica tape.

SKU: DEF-PRBRTR3D Category: Tags: , ,


DeFelsko’s PosiTector® RTR 3D captures high-resolution 3D surface imagery and common 2D/3D parameters at a fraction of the cost of drag stylus or confocal microscope instruments.

The patented PosiTector RTR 3D is ideal for measuring the surface profile of flat, curved, or irregular surfaces in the field or laboratory. Simply create a replica by burnishing Testex Tape onto the surface and insert it into the instrument. Press the two buttons and in seconds, the hand-held PosiTector RTR 3D displays imagery and measures common 2D and 3D profile parameters such as Ra, Rz, Sq and Spd, traceable to a national laboratory.

PosiTector RTR 3D Specialized Features:

  • Measures Peak Height (HL) and common 2D/3D Profile Parameters such as Ra, Rz, Sq, Spd and more
  • Calculates and records all fourteen 2D and 3D parameters with each measurement
  • Applies short and long cut-off filters and discard lengths to optimize the analysis for a specific application
  • Orients the 2D trace between horizontal, vertical, and diagonal (XY, YX)
  • Download high-resolution Surface Data Files (.SDF) for analysis in the included PosiSoft or third-party software
  • Generate two dimensional (2D) and three-dimensional (3D) thumbnail images for inclusion into reports and confirming consistent blasting results.

SDF Images:

The PosiTector RTR 3D calculates and records all fourteen 2D and 3D parameters for each measurement. From the information acquired, the gauge produces a .SDF – Surface Data File – that allows the user to evaluate the surface replica from different perspectives for different information. Using PosiSoft Desktop Software, the SDF file can be rotated and moved, to analyze a portion of the replica, and to filter the information being evaluated.

Parameters and thumbnail images can be viewed on-screen, on computer via USB, or using cloud-based app, or PosiSoft App for mobile devices. To get the most functionality out of your RTR 3D, free PosiSoft Desktop Software includes a built-in .SDF viewer for analysis of measurements – analyze a trace from the 3D plot, change filtering settings, and view 2D and 3D parameters. Create custom, professional PDF reports including measurements, photos, screen captures, and the imagery and surface profile parameters generated by the PosiTector RTR 3D. Multiple custom layouts can be saved as templates, cover pages, logos can be inserted into reports with user-selectable font sizes. Select the what to include in your report from downloaded charts, histograms, readings, time stamps, and more. Multi-batch reports can be built from one or multiple probes and instrument types.

Black and White 2D Thumbnail Images:

PosiTector RTR 3D takes a black-and-white, 2-dimensional photograph of the burnished Testex Tape. The bright areas are more highly-compressed areas of tape, which are impressions of the peaks of the surface profile, and the dark areas are lower compressed tape, or the valleys of the profile replica. This is available only in Advanced models.

3D Colour Thumbnail Images:

PosiTector RTR 3D produces 3-dimensional (3D) images of the Testex surface Replica. A low-resolution colour image is generated and displayed on the gauge display, and can be exported into inspection reports. This feature is available only in Advanced gauges.
