Thickness Gauge (Thickness Gauge)
A thickness gauge, or Thickness Gauge, is a crucial tool that accurately and quickly measures the thickness of materials without damaging them. It is suitable for quality control in various industries. At SCMA, we offer high-quality thickness gauges from leading global brands, along with a team of expert engineers to provide consultation and help you choose the most suitable measuring tool for your needs.
What is a Thickness Gauge?
A thickness gauge or Thickness Gauge is an instrument used to measure the thickness of various materials such as metals, plastics, glass, coatings, and films. It works through different technologies depending on the material type. If you ask what thickness means, it refers to the precise measurement of a material's thickness without damaging the workpiece. This measuring tool has become popular in quality control, standard checking, and condition assessment across all industries.
Types of Thickness Gauges
To cater to different applications, SCMA offers various types of thickness gauges according to material characteristics and purposes. Each type has unique working principles and applications. For more information about thickness gauges, please refer to reliable sources:
Ultrasonic Thickness Gauge
It works by sending high-frequency sound waves through the material and measuring the time it takes for the sound wave to travel back. Then, it calculates thickness based on the speed of sound in that particular material. Suitable for metals, plastics, ceramics, and glass, especially when access is limited to one side. It's commonly used to inspect pipes, tanks, and large structures to detect corrosion.
Magnetic Thickness Gauge
It operates by using a magnetic field to measure the thickness of non-magnetic coatings on magnetic surfaces such as measuring paint thickness, zinc plating, or other coatings on steel. It detects changes in the magnetic field when the probe is brought close to the coating surface for quick and accurate measurements. For car paint inspection, learn more from Paint Thickness Gauge.
Eddy Current Thickness Gauge
It uses the principle of eddy currents to measure the thickness of non-conductive coatings on non-ferrous metal surfaces. It creates an eddy current in the base metal layer and measures impedance changes to calculate thickness. Suitable for measuring anodized layers, paint coatings, or other coatings on aluminum, copper, and non-magnetic metals.
Mechanical Thickness Gauge
It measures thickness by applying physical pressure such as micrometers, calipers, or filler gauges. It directly measures the distance between two points on a material's surface. Suitable for measuring thin materials like paper, plastic film, thin metal sheets, or work requiring high accuracy and manual inspection.
Features of Thickness Gauges
SCMA selects high-quality thickness gauges with outstanding features to provide the best user experience:
