Thickness gauges are digital or LCD tools used for taking thickness measurements on parts, materials or coatings in a range of situations. Typically used in engineering, thickness gauges either use a mechanical jaw that is closed and reset to zero, then opened to fit around the material or part and then a readout is given of the measurement reading. Our range of thickness gauges is of the highest quality and sourced from leading brands such as Mitutoyo, Sauter, and RS PRO.
Different applications demand specific measurement capabilities:
Thickness gauges offer significant advantages:
Thickness gauges are thickness measurement instrument tools, with their operation varying based on type, though all aim to provide accurate dimensional readings.
These common devices, often handheld, operate by measuring the time it takes for a sound wave to travel through a material. An ultrasonic thickness gauge or ultrasonic thickness tester emits a sound pulse from its transducer, which then travels through the material to its rear surface and reflects back to the gauge. The device then calculates the material's thickness based on the elapsed time and the known speed of sound within that specific material. This method offers non-destructive testing and often requires single-sided access.
Other types of thickness gauges work through direct physical contact. A digital thickness gauge or a mechanical thickness meter typically involves a movable jaw or probe that closes around the material or coating. Once the object is securely held, the measurement is displayed, either on an analogue dial or a clear digital LCD screen. This approach is common for precise measurement of parts or coatings.
Thickness gauges are indispensable thickness measurement instrument tools, providing crucial insights where precise material assessment is critical across various industries:
They're widely used to measure metal panels, inspect windscreen glass, and identify imperfections in bodywork. Specialist tools, such as coating thickness gauges, ensure even paint application, while ultrasonic models are ideal for detecting hidden flaws beneath the surface.
In manufacturing and engineering, precision matters. Thickness gauges are essential for quality control, ensuring each component meets exact specifications. They're particularly important for safety-critical parts, like those used in aircraft, where consistency and compliance are non-negotiable.
On construction sites, thickness gauges are indispensable. They assess the integrity of walls, piping, and building materials, helping to detect early signs of wear or corrosion. In infrastructure, they're crucial for checking the condition of structural supports, such as bridge columns, to maintain safety and regulatory compliance over time.
Beyond industrial use, thickness gauges serve highly specialised fields. Jewellers rely on them to measure the thickness of precious metals and identify hidden cores. In the medical sector, coating thickness gauges help ensure surgical instruments meet hygiene and safety standards.
