Testex Dial Thickness Gauge



Testex Dial Thickness Gauge is ideal measure surface profiles.

Testex dial gauge

Profile dial gauge

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 with spring-loaded specifically designed for measuring peak and also 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.

At the firstly, measurements with the grade of tape that has the target surface profile. Secondly, 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 Compliance

Standards Governing of Replica Tape to Measure Profile as follow :

ASTM – (American Society for Testing and Materials) D 4417:

  • 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.

Who is Testex Tape

Testex Testex is the leading US manufacturer of the  Press-O-Film replica tape, replica tape reader, and also Dial thickness Gauge . Press-O-Film provides inspectors and researchers a simple way to obtain an impression of a surface. Press-O-Film (POF) consists of a layer of crush-able plastic micro foam coating onto a polyester film of highly uniform thickness. When compressing against a roughness material, Press-O-Film accurately replicates details of its surface roughness.

The impression can be studies in several ways:

A simple micro-metric dial thickness gauge can be applying to the replica for field measurement of the average maximum peak-to-valley roughness, or "profile," of a replicates surface. Also available use with digital thickness gauge such as the PosiTector RTR. It can also field-measure profile and bridge the gap between tape grades by incorporating automatic linearization. An optical profiling interferometer or confocal microscope can be uses in laboratory settings to produce maps of the replica's surface topography. This is most appropriate to study of subtle features at the micro inch (25 nanometer) level.

Standardization Testex Tape measurement

ISO 8503-5:2003 describes a field method for measuring the surface profile produces by any of the abrasive blast-cleaning procedures given in ISO 8504-2. The method uses replica tape and a suitable gauge for measuring, on site, the roughness of a surface before the application of paint or another protective coating. The method is applicable within the range of profiles cited for a given grade (or thickness) of replica tape. The commercial grades currently available permit measurement of average peak-to-valley profiles from 20 micrometres until 115 micrometres. The method is valid for surfaces that have been clean with either metallic or non-metallic abrasives. PT, Cuanli Perkasa Jaya is one of TesTex Tape worldwide distributors located in Indonesia.
