TMG universal thickness gauge for ASTM, DIN, EN & ISO standards

Made in GermanyThe TMG Thickness Gauge is a perfect choice, whether you only need to comply with one or more measurements.


The new TMG series of thickness gauges impresses with a simple construction, a very user-friendly operation and above all its high accuracy in the measurement of material thicknesses.


Very easy to operate, the measuring probe has to be simply lifted above the wire lift trigger and then lowered to the material to be measured with the specific measuring pressure of the respective measuring standard.


Its modular system makes it possible to adapt the three basic types TMG-1, TMG-2 and TMG-3 to the most common test standards. Thus a large number of ASTM, DIN, EN and ISO standards can be combined and avoid having to purchase several measuring devices. Detailed information on the possible combinations can be found in the table below.


We offer ready-made solutions for the most common materials such as elastomers, textiles, leather, nonwovens, films, films, rubber, fabrics, geomaterials, paper, paper towels and cardboard. Detailed information on all available models can also be found in the table below. Also customized special solutions are possible, please contact us for an individual offer.


The TMG thickness gauge is manufactured with only the highest quality of raw materials. For example, the massive laboratory grade granite table, stainless steel column and boom on the TMG-1 and TMG-2 stainless steel models of the TMG-3 are made of highest quality aluminum.


The use of high quality materials do not only guarantee longevity, but also high corrosion resistance even when used in rooms with high humidity. All of these features ensure a constant measuring pressure over a longer period of time, which result in consistent measuring results.


We offer ready-made configurations for the following standards:


    ISO-5084 for textiles

    ASTM D 1777 Option 2 for textiles

    ISO-23529 for rubber / elastomers   

    ASTM D3767 for rubber / elastomers   

    DIN EN ISO 12625-3 for waterproofing membranes   

    ASTM D 1777 Option 1 for fiber fabrics, knitwear, knitwear and structural textiles   

    ASTM D 1777 Option 5 for ceilings and pile fabrics   

    ISO 4593 + DIN 53370 for films and films   

    DIN EN ISO 2589 for leather   

    ASTM D 1777 Option 3 for Films and Glass Fibers   

    ASTM D 5199 for geosynthetics

    DIN EN 534 for paper and cardboard

    DIN EN ISO 3034 for corrugated board



For detailed information, please see the table below for the models available. If the appropriate standard is not available, please contact us for an individual solution.


There are two options to certify your meter: you can choose between a manufacturer calibration certificate or a DAkkS calibration, which refers purely to the dial gauge. Of course, a combination of both options is also possible to meet the highest standard. Optional software for processing the measurement data is also available.


  • Very high accuracy and excellent workmanship
  • Granite measuring bench in laboratory quality
  • Modular building block system and individual customer solutions cover every need
  • 14 preconfigured versions
  • Manufacturer calibration certificate and DAkkS calibration optional
  • Standard versions preconfigured for the most common ASTM, DIN, EN and ISO
  • Data output for processing the measurement data with the optionally available software
