To measure the thickness of evidence, various lab equipment options are available depending on the nature of the evidence.
Please visit our website for more information on this topic.
1. Calipers: Use digital or vernier calipers to directly measure the thickness of paper documents or thin objects.
2. Micrometer: A micrometer with a spindle and anvil can measure the thickness of small, flat specimens like fabric or layered materials.
3. Ultrasonic Thickness Gauge: This device uses ultrasonic waves to measure the thickness of solid objects, including metals, plastics, and composites.
4. Optical Interferometer: Employ an interferometer for extremely precise measurements of thin films, coatings, or translucent materials.
5. Atomic Force Microscope (AFM): AFM can measure the thickness of nanoscale materials with high resolution.
For more information, please visit Cell Instruments.
6. X-ray Absorption Spectroscopy (XAS): XAS can indirectly determine thickness by analyzing the attenuation of X-rays when passing through materials.
7. Scanning Electron Microscope (SEM): SEM can provide cross-sectional images that help estimate thickness by visual inspection.
Select the appropriate equipment based on the evidence type, required accuracy, and available resources for precise thickness measurements.

Ultrasonic Thickness Gauge measuring with ultrasonic wave is applicable for measuring the thickness of any material in which ultrasonic wave can be transmitted and reflected back from the other face. The gauge can provide quick and accurate measurement to various work pieces such as sheets of board and
