Testex Dial Thickness Gauge measure surface profiles.
Testex Dial Gauge used for measure the Testex replica Press-O-Film Tape on surface roughness of blast cleaned surfaces.
Testex Gauge is a precision, spring-loaded specifically designed for measuring peak and low of Testex replica tape.
The Testex imperial version gauge measure ranges from .0001″ to .050″ with 1 mil resolution. And also available for metric version unit.
First step, measurements with the grade of tape that has the target surface profile. Second step, Closest to the center of its range. Third step, put the replica tape on the center of the gauge certainly. And finally we get most accurate reading result.
Characteristics of the spring micrometer gage:
Replica tape profile characterization measurements has been performed with a gage, to having a measurement accuracy of 0.2 mil (5 microns), closing force of 3 ounces (1.1 N). And at least one anvil having a circular diameter of 0.25 inch (6.3 mm). Testex Thickness dial gauge available both an inch and an metric unit gages. They are specifically design to be used with replica tape.
Using the proper gage is essential to obtaining correct profiles.

Standards Governing of Replica Tape to Measure Profile:
- Standard Test Methods for Field Measurement of Surface Profile of Blast Cleaned Steel
NACE – International (National Association of Corrosion Engineers) RP0287:
- Standard Recommended Practice: Field Measurement of Surface Profile of Abrasive Blast Cleaned Steel Surfaces Using a Replica Tape
SSPC – the Society for Protective Coatings
ISO – International Organization for Standardization. Standard ISO 8503-5 mentioned, the preparation of steel substrates before application of coatings. And also surface roughness characteristics of blast-cleaned steel substrates. On Part 5: Replica tape method for the determination of the profile.
In cases where standards compliance is required, the full original current standard should be consulted.
