Profile Measurement

BlastOne offers multiple tools that take different approaches to measure the profile of a blasted steel surface. They are simple to use and require minimal or straightforward calibration for accuracy.

These profile measurement tools are able to detect the profile achieved on a newly-blasted surface. Typically, these profile measurements (measured in mils) are specified by the coating manufacturer.

  • INDRTRTAPEHLDER
    Recommended best practice when using the PosiTector RTR 3D is to use these specialized Replica Tape Holders. Very easy to use - just affix the replica tape to the holder, and ensure that the compressible foam is located over the hole in the holder. Once adhered, the replica tape can be simply placed into the probe with no concern about migration of the adhesive onto the probe sensors.

  • The PosiTector RTR family of instruments is DeFelsko's state-of-the-art solution for surface profile measurement and more.  Two different probe models are available and selected features are listed below:
    • Familiar.  Based on the award-winning PosiTector instrument body platform, the RTR probes are easy to master and use.
    • Capable.  State-of-the-art technology with 2 models as follows:
      • PosiTector RTR H.  This 2D version measures surface profile using Testex tape just like a spring micrometer, but with the following enhancements:
        • Automatically compensates for the thickness of the Testex film backing.
        • Using conventional Testex Coarse or X-Coarse tape, the RTR H calculates linearized measurements automatically, without the complicated averaging process required by analog spring micrometers.
        • Stores readings which can be uploaded to PosiSoft, Mac, and smartphone software for professional reporting.  Of course, you can keep the physical replica tape as well.
        • Ready-to-measure.  No calibration adjustment required for most applications.
      • PosiTector RTR 3D.  This 2D / 3D version offers the same features as the RTR H above, but with these extra features:
        • Creates a 3D image of the profile and calculates Peak Density, Peak Count and more - a total of 14 common 2D and 3D surface parameters.
        • When paired with the Advanced body, the RTR 3D can download high-res .SDF files for further analysis.
        • These 3D surface parameters are proving to be as important (if not more so) than traditional surface profile measurements for predicting coating life.  Future proof your instrument purchase against changing specifications by investing in the highly capable PosiTector RTR 3D!
        • Note:  The PosiTector RTR 3D requires Optical grade Testex tape.
    • Configurable.  Your choice of RTR probe is available separately (for use with existing PosiTector gage / body), or can be purchased as a kit with your choice of Standard or Advanced body.
    Each PosiTector Body / RTR probe kit comes complete with burnishing tool, cleaning cards, check shim(s), calibration certificate, and more!  The RTR 3D package also includes one roll of X-Coarse optical grade tape.

  • Surface Profile Standards and Shim Sets are used for checking and adjusting calibration on PosiTector SPG, PosiTector RTR (and other depth micrometer probe) instruments.  Product details as follows:
    • For the PosiTector SPG:
      • Certified Standards.  Typically used in calibration labs, these are available for any user who desires this level of verification.  Includes serialized and traceable height standards mounted to a metal plate.  Labeled in both metric and imperial units.
      • Certified Shim Set.  Premium option for everyday use with any depth micrometer using a fine-pointed probe (as well as the PosiTector SPG).  Includes 3 shims at 50/125/500 microns (2, 5, 20 mils).
      • Zero Glass Plate / Metal Shim (Non-Certified).  For training and quick checks for accuracy, each new SPG unit comes with this verification set, with replacement / additional units also available for purchase here.
    • For the PosiTector RTR: (both models unless otherwise noted)
      • Certified Shim Set.  Premium option to check Peak Height measurements for accuracy verification on the RTR series (as well as other spring micrometer replica tape readers).
      • Non-Certified Shim Set (aka Precision Plastic Shim Set). Lower cost version of the above, ideal for everyday accuracy verification.
      • Single Check Shim.  This non-certified shim comes standard with each new RTR and is available as a replacement if desired, although it is more economical to purchase the above full set.
      • Check Tape.  This reusable tape is used to verify Peak Density, and is used on the RTR 3D model only.

Producing the proper surface profile on a blasted metal surface is important with corrosion control process because it ensures the protective coating’s longevity on structural steel.

If the surface profile doesn’t have an adequate peak-valley height, it may not be able to provide a proper anchor for the coating. This can cause the coating to bubble up or fail prematurely. If there is too large a profile (higher peaks and lower valleys on the steel surface), it will require a greater amount of paint to cover the surface without any noticeable roughness.
