Thickness Gauge FAQ

What is a thickness gauge?

A thickness gauge is a device used to quickly and easily measure the thickness of a material. A thickness gauge is useful for many industries but is most commonly used in engineering and manufacturing to help ensure material thickness complies with industrial standards and regulations. As well as measuring the thickness and density of a material, a thickness gauge can be used as an additional quality assurance tool in industries such as automotive manufacturing to measure the uniformity of the material and help identify hidden damages or imperfections.

How much does a thickness gauge cost?

Different factors can affect the price and cost of a thickness gauge, such as the transducer frequency, thickness measurement application, and software capabilities. We offer free quotes and demos so that you can test and evaluate gauges pre-purchase; contact us to learn more.

What is a Hall-effect thickness gauge?

Hall-effect thickness gauges, such as the Magna-Mike&#; gauge, use a sensor that responds to changes in a magnetic field by varying a voltage. Using a small magnetic target, these gauges can accurately measure the thickness of nearly any nonmagnetic material where a probe can be placed on one side and a target, like a steel ball, on the other. Hall-effect gauges are also called magnetic thickness gauges.

How do you measure pipe thickness?

If you&#;re looking to measure the thickness of a pipe, an ultrasonic thickness gauge should be used. A handheld thickness gauge, such as the 27MG gauge, will offer accurate measurements from one side of metal pipes and parts that are thinning due to erosion or corrosion.

How do you measure metal thickness?

To accurately measure the thickness of a metal without damaging it, an ultrasonic thickness gauge should be used.

What is mil thickness? 

A mil (or thou) is a unit of thickness that equals one thousandth of an inch (0.001 inches). Example: 10 mils = 0.010 inches. Mil thickness is commonly used in manufacturing in non-metric countries to measure the thickness of various thin materials, such as paint layers, thin films, foils, plastic sheets, and coatings. 

What is micron thickness? 

A micron (µm) is a small unit of thickness that equals one-millionth of a meter (0. meters) and one-thousandth of a millimeter (0.001 millimeters). Micron is the shortened word for micrometer and is the closest metric unit to a mil (25.4 microns = 1 mil). 

How do you check paint thickness?

Ultrasonic thickness gauges can measure paint thickness nondestructively. For example, high-frequency thickness gauges such as the 72DL PLUS instrument offer features that can calculate total paint thickness and simultaneously display paint thickness measurements of up to six individual layers. Paint thickness is expressed in mils or microns.

How do you measure plastic thickness?

To measure the thickness of plastic nondestructively, a Hall-effect or ultrasonic thickness gauge should be used. The thickness of plastic is often expressed in mils or microns.

Thickness gauges are used for measuring the thickness of a material. Thickness measurement is required in many industries such as oil, gas, aerospace, automotive, pharmaceutical, food processing, production and manufacturing, as part of quality control. Thickness gauges are generally utilized in various applications related to wood, composite, metals, fiberglass, ceramics, glass, concrete, plastics, foam products, paint and other non-metallic material.

The ever-increasing use of automation, and continual advances in the production or manufacturing industries have raised demand for the use of gauging systems for improving material qualities such as strength, dimensional accuracy, flatness, surface, and formability. The use of thickness gauges has become popular because  it is an ultrasonic non-destructive technique, a viable replacement for the destructive method of measuring the thickness of a material.

Ultrasonic thickness gauges for Industrial Use

Ultrasonic thickness gauges use sound waves to non-destructively measure thickness and are a popular choice. Some traditional thickness gauges are limited to taking readings on steel and aluminum panels &#; check the materials that your gauge measures before purchasing.

Ultrasonic gauges can be used to measure the thickness of metallic and nonmetallic materials, such as steal, plastics, and glass. Applications include scanning pipes to find areas of corrosion and weak spots that may be problematic unless treated.

Today&#;s thickness gauges are simplified and advanced devices that are more sensitive than the thickness gauges of yesterday. Understanding the equipment available and how to utilize it to process control, item quality, and cost control, depending on the type of coating, thickness range, substrate material, and size and state of the part, operators can swing in any number of measuring procedures. Commonly used new advancements include magnetic measurement, ultrasonic coating thickness measurement and eddy current measurement.

Many companies today use ultrasonic method in their quality programs as it is more time efficient. They avoid the use of destructive tests which require retests or reworks. Thickness gauges that use the ultrasonic principle also replace the destructive measurement techniques for concrete, wood, and plastic applications. Regardless of the method used, operators must have knowledge of coating thickness testing when operating for the first time.
