What is it and how is it used?
A thickness gauge is used for a quick and easy measurement of the ink layer thickness on metallic surfaces. It is often referred to as an essential quality assurance tool when applying zinc to metal surfaces. As well as this, thickness gauge can be used measure body paint thickness and consistency of many objects and materials including film, paper, board, foil, tissue, and textiles.
Types of thickness gauge
There are two types of thickness gauge: ultrasonic and coating thickness gauges.
An ultrasonic thickness gauge employs sound waves to measure the thickness of a sample. This is measu by the amount of time taken for the sound to travel through the sample and then back to the meter itself.
On the other hand, a coating thickness gauge measures the thickness of non-magnetic and insulation coatings on ferrous and non-ferrous materials.
What can be measured?
There are many different objects which can be measured in a range of industries These include but are not limited to:
Medical: Tools and utensils are checked to ensure safety and sufficient protection.
Automotive: Measure the thickness of metal sheets and, the body work of cars to highlight any imperfections.
Construction: The walls and building materials are often measured to ensure to workers the walls are solid and up to standard.
Engineering: Parts are often measured to ensure the quality and consistency.
Jewellers: Measure the thickness of gold used in the jewellery as well as other metals.
Glass: The thickness of the glass in furniture and vehicles is checked.
