We combine all the research and production advantage, take advantage of years' marketing and sales experience in global market, and contribute to offering most qualified competitive products and service to international markets from China. Our products are composed of all kinds of metal and non-metal quality control equipments, such as portable hardness testers, portable X-ray flaw detectors, digital radiography imaging system,ultrasonic flaw detectors, magnetic particle flaw detector,coating/painting thickness gauges, ultrasonic thickness gauges, surface roughness testers, and gaussmeter, and all of their accessories such as ultrasonic transducers, test blocks, and x-ray films. 

The SF-BT series through-coating ultrasonic thickness gauge utilizes the principle of ultrasonic thickness measurement to achieve portable, non-destructive, rapid, and precise measurement of various material thicknesses and sound velocities as a high-precision thickness gauge. It is suitable for measuring the thickness of various materials that allow ultrasonic waves to propagate at a constant speed internally and reflect from their back surfaces, such as various metals (steel, aluminum, copper, etc.), glass, plastics, and other materials. It is commonly used in machinery, petroleum, chemical, metallurgy, aerospace, aviation, automotive manufacturing, and other fields.


Product Advantages
The SF-BT Series, with its high precision,through-coating measurement capability, efficient operation, and durability, is an ideal tool in industrial inspection, especially suited for users requiring fast, non-destructive, and multi-scenario testing.


Key Features:
- Measures the thickness of substrate metal layers (e.g., steel, cast iron, aluminum, copper) through coatings without damaging the coating.

- Suitable for metals (steel, cast iron, aluminum, copper, etc.), plastics, ceramics, glass, fiberglass and other ultrasonic-conductive materials.

- Sound velocity calibration capability using known thickness references for improved accuracy.

- Coupling status indication function .
- High-definition LCD display for low-light environments.
- Energy-saving features including auto-sleep and auto-power-off.
- The aluminum-magnesium alloy casing is sturdier, more compact, portable, and offers high reliability and durability, making it suitable for harsh operating environments with resistance to vibration, shock, and electromagnetic interference 

Application
The working principle of the coating thickness gauge is primarily based on ultrasonic pulses emitted by the probe of an ultrasonic thickness gauge, which travel through the tested object, reflect back to the probe upon reaching material interfaces, and determine the thickness of the material by measuring the propagation time of ultrasonic waves, enabling it to address the majority of challenging measurement requirements.


Application Fields
Metal Processing Industry: The through-coating thickness gauge can penetrate various coated metal plates, pipes, and rods to accurately measure substrate thickness, analyze thickness distribution and uniformity, and provide quality control support for metal processing.

Petrochemical Industry: It can measure the wall thickness of storage tanks, pipelines, and other coated equipment to assess safety and service life. Additionally, it monitors corrosion-induced thinning during operation, offering critical data for maintenance and preservation.

Shipbuilding Industry: In ship manufacturing and repair, the gauge penetrates coatings on hulls and plates to measure structural thickness, evaluating vessel strength and durability.

Power Industry: For electrical facilities, it penetrates coatings to measure the thickness of transformers, generators, and other equipment, ensuring operational safety and reliability.

Core Value of Through-Coating Thickness Gauges:
Across industries, the device delivers non-destructive, efficient, and high-precision solutions, overcoming limitations of traditional methods such as coating damage, inefficiency, and data management challenges.
It has become an indispensable tool for industrial quality control and safety assurance
