Welding gauges are inspection gauges used for checking alignment, checking dimensions before welding, verifying weld dimensions, and checking porosity of welds.

TC10S Coating Adhesion Tester is a new type of instrument, which is mainly used in the detection of anti-corrosion coating adhesion in the construction of high-speed rail projects. The surface coating adhesion of steel pipes and iron plates is a necessary testing instrument for quality inspection and construction units.

Digital Rockwell hardness tester, suitable for hardness measurement of quenched, quenched and tempered, annealed, chilled castings, malleable castings, hard alloy steel, aluminum alloy, copper alloy, bearing steel, etc.

The Brinell hardness tester can measure the Brinell hardness of ferrous metals, non-ferrous metals, unquenched steel, softer materials and bearing alloy materials; it has a wide range of applications and is suitable for precise measurement of parallel planes, and the measurement of curved surfaces is stable and reliable.

PAV-1 Asphalt Pressure Aging Test Chamber is a special equipment for evaluating the aging condition of asphalt in natural environment. The system includes asphalt pressure aging container box and asphalt vacuum degassing box.The Pressure Aging Vessel (PAV) provides simulated long term aged asphalt binder for physical property testing. Asphalt binder is exposed to heat and pressure to simulate in-service aging over a 7 to 10 year period.

Handheld Magnetic particle detector is a small portable non-destructive testing instrument with clear crack display, reliable performance, stable and easy operation. The instrument uses a coil to be wound directly on the probe to generate an induced magnetic field to magnetize the workpiece. The device has small size, light weight, large lifting force and adjustable movable joints. Suitable for flaw detection of flat welds, fillet welds, steel pipes, pressure vessels, pipes, shafts and complex shapes.
