TQC Sheen Defelsko PosiTector RTR Tape Reader – Standard and Advanced Models

Digital Profile Measurement with Replica Tape for Surface Texture Validation

The TQC Sheen Defelsko PosiTector RTR is a portable, electronic surface profile gauge that accurately measures peak-to-valley height on blasted steel or textured coatings using Testex® Press-O-Film® replica tape. It helps quality control teams assess surface roughness and confirm surface preparation standards before coating applications.

Designed to operate in challenging industrial settings, the RTR combines simplicity and durability with advanced measurement capabilities. The 2.8″ color touchscreen, rugged IP65-rated enclosure, and intuitive menu system make it equally suited for shop or field use. With no calibration required for most applications, setup is fast and straightforward.

Both the Standard and Advanced models offer on-board storage, Bluetooth and WiFi connectivity, and compatibility with the full range of PosiTector probes—making this a flexible and future-proof investment.

Whether you’re verifying blast profiles for pipeline coatings or qualifying surfaces for critical aerospace applications, the PosiTector RTR delivers precise, traceable results that conform to international standards like ASTM D4417, ISO 8503-5, and NACE SP0287.

Why Surface Profile Measurement Matters

Improper surface roughness can lead to coating adhesion failures, corrosion under coatings, or premature degradation in aggressive environments. The PosiTector RTR provides essential surface profile data, helping ensure that blast-cleaned surfaces meet industry specifications—improving coating performance and reducing rework or failures.

How to Use the PosiTector RTR Tape Reader

1. Prepare the surface using cleaning putty to remove dust or debris.
2. Burnish a piece of replica tape onto the surface using the included tool.
3. Measure by inserting the tape into the micrometer to capture peak-to-valley height.
4. View & Record results on the digital display and store or transfer data as needed.
