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.

High-Precision Thickness MeasurementThis gauge offers unparalleled accuracy, enabling industrial users to measure film and sheet thickness with a genuine reading to 1 micron. The manual dial gauge provides instant results, minimizing errors and ensuring standards are met according to IS 2508:1984 and relevant protocols. The device's portable, compact design makes it ideal for bench-top or desktop usage in laboratories or on the factory floor.
Rugged Build and User-Friendly OperationEngineered with a stainless steel body and powder-coated finish for superior corrosion resistance, the gauge endures demanding operating environments. It's operate using a lever press with spring recovery, and features an ergonomic ABS handle for comfortable use. No power supply is needed, allowing efficient operation even in areas without electricity. Pre-calibration as per IS standards simplifies setup and ensures consistent performance every time.
FAQ's of Polythene Sheets Micron Thickness Measuring Gauge:
Q: How do I operate the Polythene Sheets Micron Thickness Measuring Gauge?
A: The gauge is operated manually using a lever press. Place your specimen (minimum 25 x 25 mm) on the base, align it under the 6 mm contact surface, and press the lever. The dial gauge immediately displays the thickness measurement up to 1 mm spindle travel.
Q: What materials can this measuring gauge be used with?
A: This instrument is designed primarily for measuring the thickness of polythene sheets, plastic films, and bags within the 10 to 500 micron range. It is suitable for most materials conforming to these specifications used in packaging and industrial applications.
Q: When should I re-calibrate the gauge?
A: The unit is shipped pre-calibrated as per IS Standards. It is recommended to check and recalibrate periodically-either annually, or after any significant physical shock or suspected result drift-to maintain optimal accuracy.
Q: Where can this gauge be used?
A: This thickness measuring gauge is suited for industrial and laboratory environments, specifically in quality control departments, manufacturing plants, and inspection labs. Its portable design allows for desktop or bench-top mounting as needed.
Q: What is the process for taking a measurement?
A: Simply prepare a single specimen (minimum size 25 x 25 mm), align it on the measuring platform, and use the lever press. The flat contact surface and controlled spindle ensure consistent compression for reliable readings, visible instantly on the dial gauge.
Q: What are the key benefits of using this measuring gauge?
A: Users benefit from high measurement accuracy (1 micron), portability, corrosion resistance, and a maintenance-free manual operation-no power supply required. Its robust construction ensures long-term reliability, while easy operation boosts efficiency in quality assurance tasks.
