- Various forms of test data can be searched, exported and printed out
Note: The described features should be in line with Table 1: Test Parameters.
Note1: The Repeatability refers to the repeatability within the test range.
Test Principle
The pre-conditioned specimen is placed on a flat test plane, the pressure foot which is paralleled to the test plane will drop down on the upper surface of the specimen with certain pressure applied on. The displacement sensor with the pressure foot will detect the space between the upper and lower surface of the specimen, which is the thickness of the specimen.

FAQ's of Off-line Thickness Measurement for PE film and aluminum foil sheets:
Q: How does the contact probe micrometric measurement work for thickness testing?
A: The system uses a precision contact probe to measure the thickness of PE film and aluminum foil sheets while the sample rests on an anti-static base. The probe moves across the sample, capturing highly accurate thickness values (0.001 mm) with each measurement.
Q: What are the calibration options and when should I calibrate the device?
A: Both automatic and manual calibration options are provided. Calibration should be performed initially during setup, after any maintenance, or when measurement accuracy needs to be verified, in line with your laboratory's standard procedures.
Q: Where can this thickness measurement equipment be installed and used?
A: This benchtop system is designed for use in indoor, dust-free laboratory or quality inspection environments. On-site installation and training services are available to help ensure proper setup and user proficiency.
Q: What is the process for measuring samples and how many can be tested per day?
A: The system accommodates specimens up to 700 mm width by 200 mm length, allowing up to 200 samples per day. Simply align the sample using the guides, initiate the measurement via the digital LCD or control software, and export the results upon completion.
Q: What are the advantages of using this system for thickness measurement?
A: Benefits include high-precision measurements, automatic and manual calibration, automatic data saving, easy integration with laboratory systems via USB or RS232, programmable test parameters, and a robust, low-maintenance design.
Q: What safety and compliance standards does the equipment meet?
A: The device is equipped with overload protection, an emergency stop, and is certified to both ISO and CE standards, ensuring operator safety and regulatory compliance throughout use.
