1. Appearance verification:
    1.Test method:Visual observation, feel and experiment.
    2.Inspection requirements:
    2.1.The coating should be firm, the surface should be smooth, the color should be uniform, there should be no fading, falling off, scoring and other defects.
    2.2.The measuring surface and the base surface shall be free of rust, burr, black spot, scratch and other defects.
    2.3.Exhaust tank, vent hole should be clean, no burrs, iron filings and heat treatment residual salt and other phenomena affecting the performance.
    2.4.The solder and adhesive used to connect cemented carbide should be firm, and there should be no obvious overflow after connection.
    2.5.The surface of synthetic materials such as guide and anti-knock should be smooth, the connection should be reliable, and there is no obvious concave and convex phenomenon.
    2.6.The lettering on the handle should be correct, even, clear and neat.

    2.7.The pipe connection should be reliable, and the performance should not be affected by the leakage caused by the damage of the plastic hose or the air resistance caused by bending.

    Second, material and hardness testing
    1.Inspection requirements:The inner (outer) diameter probe, nozzle body, locating block and calibrating gauge are made of alloy steel (SKS31), the hardness of the measuring surface should not be less thanHRC60Above, the proofreading gage will undergo stability treatment.
    3. Surface roughness verification
    1.Inspection requirements:Roughness of probe, nozzle body, positioning block and working surface≤0.16Ra/μm; Check the roughness of the ring gauge working surface≤0.08Ra/μm.
    As a precision parts size pneumatic measurement equipment manufacturer, we have19+Years design experience engineer, can provide a variety of measurement solutions. Produced pneumatic probes were used Germany imported steel, to ensure the real material, after the original salt bath heat treatment, high temperature1500°Quench, wear proof, liquid nitrogen-180°Deep cooling to remove internal stress, prevent deformation, manual grinding, ensure micron accuracy.
