Geomembrane thickness tester

This thickness gauge is meticulously designed and manufactured according to the thickness requirements specified in GB/T6672-2001 "Determination of Thickness of Plastic Films and Sheets - Mechanical Measurement Method" and SL 235-2012 "Standard Test Procedures for Geotechnical Synthetic Materials".  The gauge has a simple structure, is easy to use, portable, and can be used for handheld measurements.

Application

Used to determine the thickness of smooth geomembrane and other plastic films under specified pressure and time. The sample is placed on the reference plate, and after a specified pressure is applied to the sample for a certain period of time with a circular press foot parallel to the reference plate, the vertical distance between the two plates is measured, and the geomembrane thickness is expressed as the average value of the test results.

Test Procedures

1. Sample Placement: Lay the sample to be tested flat on the measuring platform, ensuring it is clean, tidy, and free of wrinkles. Multiple thickness measurements can be taken by manually moving the sample.

2. Testing Principle: The film thickness gauge uses a mechanical contact testing method, measuring the thickness of the film material using a displacement sensor.

3. Measurement Procedure: Before testing, the instrument's measuring head rests on the equipment's anvil. The sensor reads the initial displacement value of the measuring head. After lifting the measuring head, place the sample on the anvil. The measuring head then rests on the sample with the same pressure. The sensor reads the displacement value of the measuring head. The difference between the two displacement values is the thickness of the sample.

4. Reading Results: After the measurement is completed, the measured thickness value will be displayed on the thickness gauge's screen. Record the measurement results, including the location of the measurement point, date and time, and any factors that may affect measurement accuracy.
