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.

The Testex tape process of measuring surface profile has been used for over 50 years. It is a simple, reliable, and repeatable way of determining surface profile parameters. DeFelsko acquired the Testex tape line and incorporated it into their range of instruments, for increased compatibility and greater convenience for inspectors. DeFelsko is now offering updated packaging in 50-piece packs while continuing to offer the legacy roll packaging. NOTE - the profile ranges are not entirely the same between them - their respective ranges are shown under the Product Description tab. Tape options include the following:- Conventional Testex Press-O-Film Tape grades.
- Use with analog spring or digital micrometers or with the PosiTector RTR H probe.
- Optical Grade Testex Press-O-Film Tape Grades
- Use with PosiTector RTR 3D probe. Provides surface data files (.sdf) that allow both 2D and 3D measurements.
- Conventional Testex Press-O-Film Tape grades.

INDRTRTAPEHLDERRecommended 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.INDRTRTAPEHLDERRecommended best practice when using the PosiTector RTR 3D is to use these specialized Replica Tape Holders.

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.

BlastOne offers all accessories and replacement parts for DeFelsko testing instruments. The PosiTector Surface Profile Gauges have replaceable tungsten carbide tips and are available as follows:- 60° Angle for ASTM (USA) applications, used in the Integral, Standard Cabled, and Convex Cabled probes.
- 30° Angle for AS 3894.5-C (Australia) applications, also used in the Integral, Standard Cabled, and Convex Cabled probes.
- CS Tip for Textured Coatings probes.
- TS Tip for Concrete Surface probes.
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.
