Which tool is used to check the size of atomizer sprayer plate orifices?

The GO/NO-GO gauge is specifically designed to check the size of orifices in components such as atomizer sprayer plates. This gauge helps ensure that the orifices meet specified tolerances by providing a simple pass/fail measurement. If the "GO" end of the gauge fits through the orifice, it confirms that the size is acceptable; if the "NO-GO" end does not fit, it indicates that the orifice is oversized. This tool is essential in applications where precision is critical, such as in fuel injection systems where proper atomization is necessary for optimal combustion.

Other tools like calipers and micrometers can measure diameters and dimensions, but they do not provide the same immediate check of tolerances for functional components as a GO/NO-GO gauge does. A measuring tape is typically used for larger measurements and would not be suitable for the precise checks required for orifice sizes.
