The Analog Dial Thickness Gage is a traditional, robust snap gage specifically engineered for measuring the surface profile created by Testex Replica Tape. These gages are uniquely manufactured with the precise closing force, anvil dimensions, and parallelism specifications required by international standards for accurate replica tape measurement. It provides a simple, direct analog reading of the compressed tape thickness, which, after manual subtraction of the 50 µm (2 mils) backing film, yields the surface profile height.
- Traditional analog dial snap gage
- Meets required closing force specifications
- Choice of Mils or Microns units
− Features
- Precision Design for Replica Tape: Unlike generic thickness gages, this model is custom-designed with the correct anvil/contact point dimensions, required parallelism, and mandated 1.1 N closing force to ensure compliant and accurate measurement of the compressible replica tape.
- Dual Unit Options: Available in models factory-calibrated to display readings either in Mils (mils) or Microns (µm), allowing the user to select the preferred unit based on local standards or project specifications.
- Optional Certification: Available with an optional Long Form Certificate of Calibration (models RTMMILCERT and RTMMICCERT) traceable to a national metrology institute, which is essential for fulfilling strict ISO or in-house quality control requirements.
- Mechanical Reliability: Operating purely on mechanical principles, the gage offers high durability and reliability in harsh field environments and does not require batteries or external power sources.
- Compatible with Legacy Method: It is the standard instrument for use with Testex Replica Tape, perfectly suited for technicians adhering to traditional ASTM D4417 procedures that require manual calculation and the overlap range averaging technique.
+ Standards
+ Application & Standards
The Analog Dial Thickness Gage is used by coating inspection personnel to measure the physical replica created by Testex Press-O-Film Tape following abrasive blast cleaning. It is a critical tool for quantifying the peak-to-valley surface profile height on steel and other substrates to ensure that the required roughness for optimal adhesion is achieved before painting or coating application, in compliance with international standards for corrosion prevention.

+ FAQs
What is the main difference between this Analog Gage and the Digital Micrometer?
The Analog Gage is a mechanical tool that requires the operator to manually subtract the 50 µm (2 mils) backing film thickness and perform any necessary overlap range averaging, while the Digital Micrometer automates these calculations.
Why is the closing force important for replica tape measurement?
The closing force of 1.1 N is critical because it ensures the soft, compressible foam on the replica tape is measured consistently according to the specified ASTM and ISO standards, guaranteeing high measurement accuracy and repeatability.
Does this gage come with a calibration certificate?
Yes, a Long Form Certificate of Calibration traceable to a national metrology institute is included with the Certified models (RTMMILCERT and RTMMICCERT) to support quality system compliance.
How is the true surface profile height calculated using the Analog Dial Gage?
The measurement displayed on the dial is the total thickness of the compressed foam plus the incompressible backing film. To get the true profile height, the operator must manually subtract the 50 µm or 2 mils backing thickness from the reading.
What is the “overlap range” procedure associated with this analog measurement?
When a reading falls within the 38 to 64 µm (1.5 to 2.5 mils) overlap range of the Coarse and X-Coarse tapes, the operator must take a second reading with the other tape grade. The average of the two compliant readings is then recorded as the final profile height.
