Standard Air Ring Gauges are available in the size range:
6.00 - 50.8mm (0.236 - 2.00in)
They may be bench mounted or connected to the display unit directly or with a 90º adaptor.
They provide a quick, highly accurate way to measure shafts for diameter, parallelism & ovality.
Shafts can be scanned for slight variations, which would be difficult to detect using other means.
Offset jets are available to allow measurements to be made close to the shoulder.
