Its dual servo motor system drives a precision ball screw to lower the presser foot at a controlled speed, applying test pressures of 2 kPa, 20 kPa, or 200 kPa without operator influence. The instrument is suitable for manufacturers, independent testing laboratories, and construction quality control departments that need to verify geosynthetic roll materials against project requirements before shipment.\u003c\/p\u003e\n\u003cp\u003eAll seven test configurations are integrated into one instrument, eliminating the need for separate thickness gauges for geotextiles, uniform barriers, and non-uniform barriers. Interchangeable 100 cm² and 25 cm² presser feet accommodate planar materials, while specialized coaxial presser points measure polymeric and bituminous barriers, including applications involving forces as low as 0.1 N. Technicians select the required test method through the industrial touchscreen, after which the instrument automatically performs the loading sequence, dwell period, and measurement.\u003c\/p\u003e\n\u003cp\u003eThickness measurements are captured by a dial gauge offering 0.001 mm resolution over a 0 to 10 mm range. Integrated control software records each result for statistical evaluation and calculates averages across ten specimens, as required by most applicable test methods. Completed test data can also be transferred through the network to a Laboratory Information Management System (LIMS) or quality database. With overall dimensions of 1150 × 670 mm, the QualiGTX™ TG A provides extensive testing capabilities while maintaining an efficient laboratory footprint.\u003c\/p\u003e\n\u003ch2\u003eAutomatic

influenced by the pressure applied during measurement rather than being a constant material dimension. Nonwoven geotextiles, geonets, and drainage cores can undergo measurable compression under load. For this reason, a meaningful thickness result must identify the applied pressure, presser foot contact area, and dwell time. Relevant test methods establish specific presser foot dimensions and loading pressures, then measure the perpendicular distance between the reference plate and presser foot after maintaining the prescribed load for a defined period. The QualiGTX™ TG A mechanically controls these testing conditions to minimize variations caused by manual operation.\u003c\/p\u003e\n\u003cp\u003eThe pressure applied to a specimen is determined by the relationship between the applied force and the contact area of the presser foot. The 100 cm² presser foot has a weight of 2041 g and applies a force of 20 N, producing a pressure of 2 kPa across its contact surface. Similarly, the 25 cm² presser foot weighs 510.2 g and applies a force of 5 N, generating the same 2 kPa pressure over its smaller contact area. This arrangement maintains comparable testing pressure across both configurations. The dual servo motors and precision ball screw mechanism provide additional calibrated loading to achieve pressures of 20 kPa and 200 kPa, maintaining accuracy within ±0.1 kPa and ±1 kPa, respectively.\u003c\/p\u003e\n\u003cp\u003ePolymeric and bituminous barriers with irregular surfaces require an alternative measurement arrangement. A conventional flat presser foot may rest on raised surface areas rather than accurately measuring the material thickness. To address this, the instrument uses matching coaxial presser points with a radius of 1 ± 0.1 mm, allowing the contact points to seat against the specimen surface. Coaxial point forces of 0.6 N and 0.56 N are applied across three predefined test modes, covering applied loads from 0.1 N to 0.5 N and from 0.5 N to 1.0 N. The two presser points apply force through the sheet, while the dial gauge measures their resulting separation with 0.001 mm resolution.\u003c\/p\u003e\n\u003ch2\u003eAutomatic Geosynthetic Thickness Gauge - QualiGTX™ TG A Technical Specifications\u003c\/h2\u003e\n\u003ctable class=\"table table-style-align-center\" align=\"center\" border=\"1\" cellspacing=\"0\" cellpadding=\"0\" width=\"612\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eTest Modes\u003c\/td\u003e\n\u003ctd\u003e7 thickness test configurations in one instrument\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePresser Foot Area (Geospacers and Drainage Geocomposites)\u003c\/td\u003e\n\u003ctd\u003e100 cm²\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePresser Foot Area (General Geosynthetics)\u003c\/td\u003e\n\u003ctd\u003e25 cm²\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePresser Point Radius\u003c\/td\u003e\n\u003ctd\u003e1 ± 0.1 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasuring Foot Diameter\u003c\/td\u003e\n\u003ctd\u003eφ10 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e100 cm² Presser Foot Load\u003c\/td\u003e\n\u003ctd\u003e20 N (2 kPa ± 0.01 kPa; foot mass 2041 g)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e100 cm² Foot, Second Load Stage\u003c\/td\u003e\n\u003ctd\u003e20 kPa ± 0.1 kPa\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e100 cm² Foot, Third Load Stage\u003c\/td\u003e\n\u003ctd\u003e200 kPa ± 1 kPa\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e25 cm² Presser Foot Load\u003c\/td\u003e\n\u003ctd\u003e5 N (2 kPa ± 0.01 kPa; foot mass 510.2 g)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e25 cm² Foot, Second Load Stage\u003c\/td\u003e\n\u003ctd\u003e20 kPa ± 0.1 kPa\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e25 cm² Foot, Third Load Stage\u003c\/td\u003e\n\u003ctd\u003e200 kPa ± 1 kPa\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCoaxial Point Force, Mode 1\u003c\/td\u003e\n\u003ctd\u003e0.6 N ± 0.1 N; applied pressure 20 kPa\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCoaxial Point Force, Mode 2\u003c\/td\u003e\n\u003ctd\u003e0.56 N + 0.05 N; applied force 0.5 N to 1.0 N\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCoaxial Point Force, Mode 3\u003c\/td\u003e\n\u003ctd\u003e0.56 N + 0.05 N; applied load 0.1 N to 0.5 N\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDial Gauge Measuring Range\u003c\/td\u003e\n\u003ctd\u003e0 to 10 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDial Gauge Resolution\u003c\/td\u003e\n\u003ctd\u003e0.001 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasurement Accuracy\u003c\/td\u003e\n\u003ctd\u003e0.001 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDivision Value\u003c\/td\u003e\n\u003ctd\u003e0.001 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDrive System\u003c\/td\u003e\n\u003ctd\u003eDual servo motors with high-precision ball screw\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eControl System\u003c\/td\u003e\n\u003ctd\u003eIndustrial touchscreen microcomputer with proprietary test software\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eData Handling\u003c\/td\u003e\n\u003ctd\u003eMulti-reading averaging, result storage, network upload\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVoltage\u003c\/td\u003e\n\u003ctd\u003eAC 220 V, 50 Hz (110V is also available)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions (W × D × H)\u003c\/td\u003e\n\u003ctd\u003e1150 × 670 × 1280 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNet Weight\u003c\/td\u003e\n\u003ctd\u003e180 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Qualitest USA LC","offers":[{"title":"Default Title","offer_id":53459592249655,"sku":null,"price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0786\/1859\/1543\/files\/automatic-geosynthetic-thickness.webp?v=1793362630","url":"https:\/\/qualitest.us\/es\/products\/automatic-geosynthetic-thickness-gauge","provider":"Qualitest USA LC","version":"1.0","type":"link"}
