Pros and Cons of Coating Thickness Gauge


Before knowing the advantages and disadvantages of a coating thickness gauge, understand what the device does. It is a device that measures the thickness of a dry film. The most critical form of measurement when it comes to coatings industries is the measurement of dry film coating. The measurement readings determine the life expectancy of the layer.

Advantages
1. It has two forms: The coating thickness gauge machines come in two forms, a mechanical one and a digital one. Mechanical ones are perfect for working in high-risk areas like underwater or flammable zones. Digital ones have a design which enables it to provide accurate measurements on any substrate, whether metallic or non-metallic.

2. Accuracy: With the advancements in science and technology, designers manufacture coating thickness gauges that are very accurate. However, it depends on the level of precision you need in your work. If you are buying a device from a renowned company, then you will get the most precise readings every time.

Disadvantages

1. The eddy current principle: Even after resorting to single-coil probe for the eddy current law, a flow of alternating current circulates in the substrate. As a result, magnetic fields start to form which influences the coating thickness probe. It also brings about changes in the electrical impedance of the coil.

2. Expensive: Every commercial person will want a coating thickness gauge which gives accurate readings. Several manufacturing companies are producing the machine, but only the expensive ones are accurate. When it suits your business, you are ready to make expenses, but if the product is too costly, then it can hurt the industry.

Choose wisely

Always remember to calibrate the coating thickness gauge before you test. The calibration process will ensure that a device does not read a different coating value on two different metal surfaces having the same level of coating. Keep the pros and cons of the coating thickness gauge in mind while buying so that you get the best deal for your investment.

Advantages of Universal Testing Machine

The main advantage of investing in a universal testing machine is that the device can be used to test the strength, durability, and suitability for most any material. A universal testing machine has the capability to pull, compress, bend, or stretch material to its breaking point. It is primarily used by laboratories that manufacture and or mould different types of plastics. A universal testing device features one or two vertical columns mounted on a base. A second horizontal plate contains attachments that are used to hold the sample and slides up and down during stress testing samples. Dual vertical column machines are preferred by most laboratories as they can handle larger samples in terms of size and weight. Determining tensile strength is the most common test performed in a universal testing machine. This is done by holding one end of a sample in place while the other is pulled away until two sides are torn apart. The same process is used for testing flexural str

Uses for Universal Testing Machine

Universal testing machine or UTM is aptly named as it can perform various types of tensile and compression tests on different materials. There are also many different terms used to refer to a UTM that you will commonly hear in the industry, among the most popular of which are a tensile tester, bend tester, and compression tester. Some types of UTMs are stripped of some capabilities and/or are marketed to specific sectors, like texture analyzers for food, peel tester for adhesives, labels, and tapes, and top load compression tester for pipes and packaging. True UTMs can perform all of these and more. They are great multi-purpose instruments for any QC or R&D laboratory. The following are only a few common uses for UTMs: Tensile testing – One of the most common applications for UTM, a tensile test measure how strong a material is, how long it can stretch, and how stiff it is as the material is pulled apart until breaking point. Compression testing – Compr

Importance of Ultrasonic Pulse Velocity Test in The Construction Industry

Image
In the construction industry, it is important to ensure that structures are built properly using the highest-quality materials and construction methods. Hence, certain tests must be conducted to ensure the quality of certain materials. The ultrasonic pulse velocity test is one of the most essential tests designed to determine the quality of natural rock and concrete. This testing method is preferred because it is non-destructive and it is conducted on site, saving builders a lot of time and money. In an ultrasonic pulse velocity test, the quality and strength of rock or concrete is determined by measuring the velocity of the ultrasonic pulse, which passes through the natural rock formation or concrete structure. The test is conducted using specialised equipment that generates a pulse of ultrasonic wave and measuring the time it takes for that pulse to go through the concrete. A high velocity indicates that the material is continuous and high-quality, and a slower velocity may
