Coating & Material Thickness Gauges

Coating and material thickness gauges are precision instruments used to measure the thickness of coatings, platings, or substrates, ensuring that protective and functional layers meet design specifications. GAO Tek’s gauges provide high-resolution measurements using non-destructive methods such as magnetic induction, eddy current, or ultrasonic technologies. Our instruments are designed to deliver reliable readings even in harsh industrial conditions.

These gauges are widely applied in automotive manufacturing to ensure paint thickness uniformity, in aerospace for corrosion protection monitoring, in shipbuilding for coating validation, and in industrial settings where insulation or plating quality must be verified.

These instruments are also referred to as film thickness gauges, coating meters, or material thickness testers.

Flaw Detectors

Flaw detectors are designed to identify internal or surface defects such as cracks, inclusions, voids, or porosity within metals, composites, and other materials. GAO Tek’s flaw detectors use advanced ultrasonic or electromagnetic testing techniques to deliver accurate defect detection without damaging the material. Rugged and portable, they are suited for both field inspections and laboratory environments.

They are commonly applied in pipeline integrity testing, aerospace component inspections, structural weld evaluations, and manufacturing quality control to prevent costly failures and ensure compliance with industry standards.

Flaw detectors are also known as ultrasonic flaw detectors, defect analyzers, or nondestructive testing (NDT) flaw testers.

Crack Detectors

Crack detectors are specialized devices engineered to locate and evaluate cracks in structural materials, often using magnetic particle inspection, eddy current, or dye penetrant methods. GAO Tek offers crack detectors that provide reliable detection for both surface and subsurface cracks in metals, concrete, and other critical materials.

Applications include bridge and tunnel inspections, railway track monitoring, industrial machinery maintenance, and structural safety assessments in civil engineering projects.

These instruments are also referred to as crack testers, fissure detectors, or surface crack analyzers.

Gloss Meters

Gloss meters measure the reflective properties of a surface by quantifying the amount of light reflected at a specific angle. This measurement is essential for evaluating surface finish quality, aesthetic appearance, and consistency in coatings or materials. GAO Tek’s gloss meters are designed with wide measurement ranges, high repeatability, and digital reporting features.

They are frequently used in the automotive industry for paint finish evaluations, in plastics for surface uniformity checks, in flooring and construction for material appearance validation, and in industrial coatings to maintain consistent gloss levels.

Gloss meters are also referred to as sheen meters, reflection meters, or surface gloss testers.

Hardness Testers

Hardness testers measure a material’s resistance to indentation or deformation under applied force, offering a key indicator of mechanical properties such as strength and durability. GAO Tek supplies a wide selection of hardness testers, including Rockwell, Brinell, Vickers, and durometers, designed to accommodate metals, plastics, rubbers, and composites.

Applications include metallurgical analysis in laboratories, quality control in production lines, and material testing in aerospace, automotive, and construction industries. These testers help determine whether materials can withstand mechanical stresses in real-world applications.

They are also known as Rockwell testers, Brinell hardness testers, or durometers depending on the testing method.

Thermal Imagers & Industrial Endoscopes

Thermal imagers detect temperature variations through infrared radiation, providing non-contact diagnostics of electrical systems, mechanical components, or building structures. Industrial endoscopes, by contrast, allow visual inspection inside confined or inaccessible areas using flexible probes and cameras. GAO Tek offers durable thermal imagers and endoscopes designed for challenging industrial environments.

They are used in electrical inspections, mechanical fault detection, HVAC diagnostics, and building maintenance to prevent failures and improve safety. Endoscopes are particularly valuable in aerospace, automotive, and pipeline industries where direct access is not possible.

They are also referred to as infrared cameras, borescopes, or inspection scopes.
