Many products are purchased based on appearance, style, perceived durability and finish. For the finish, gloss, color and coating thickness is considered. Coating used to be applied only to prevent corrosion. With the advancement of technology, coating has now become an important way to evaluate the overall performance of a product.
Coating thickness has become important in assessing a product’s quality, life cycle, usefulness and advantages over other similar products. It also is considered in cost control and process control. Surface measurement, film thickness, sheet thickness and coating thickness are measured using a variety of instrument measurements and devices. Knowing the equipment for coating thickness measurement, how to use it, and the right tool measurement is essential in any coating operation.
To determine the best method to use for a given coating measurement requirement, the following are first determined: the type of coating, the coating thickness range, including the substrate material, the cost of the equipment and the shape and size of the part.
With advanced scientific measurement technology, there are many devices specially designed to generate accurate readings for a wide range of coating thickness applications. Aside from design and accuracy, the devices can be found in various bench-top, hand-held, and multi-purpose models that can be used in electro-less nickel plating, anodizing, galvanizing, powder coating and plating applications.
To quickly and accurately measure the coating thickness of both non-ferrous and ferrous metals, eddy current and magnetic principles are used in making fully electronic, rugged coating thickness gauges.
There are coating thickness gauges that measure coating thickness on steel and iron that have ferro-magnetic substrates. The tool measures coating thickness that should be non-magnetic enamel, paint, chrome, aluminum, brass or copper.
Other coating thickness measurement gauges are capable of measuring coating thickness on non-magnetic substrates like aluminum alloys, aluminum, copper, bronze, rustproof magnetic steels and brass tins. The gauge measures that the plastics, enamel, paint, ceramics and anodized coatings used are electrically insulating.
Coating thickness gauges are commonly used in the automotive industry. These paint coating thickness meters and paint gauges are used to easily detect refinished surfaces. Buyers of this type of coating thickness gauges or paint meters are usually auto body shop owners, body shop suppliers, car dealerships, black book vehicle or car buyers, insurance inspectors and appraisers, professional car buyers, auto auctions or car auction operators, and other professionals that need fast, precise and accurate paint coating thickness or surface measurements
Insurance appraisers and inspectors at car auctions often make use of coating thickness gauges to evaluate the condition and quality of the paint coating of the vehicles before they are insured, since one of the most popular methods of selling refinished vehicles is through car auctions. Most car buyers are not aware of the quality of a vehicle’s paint refinishing job, if the buyer does not know the actual value of the refinished car purchased, it can become very costly in the long run.
For those intending to purchase coating thickness measurement gauges, research more on the kind of gauge that will fit your application. Consider the cost and price of the item. You need to maximize the use and purpose for purchasing the coating thickness, sheet thickness device or instrument, and make use of the right tool measurements and methods.
