Miniature Air Ring Gauges

Miniature Air Ring Gauges are available in the size range:

1.50 - 6.00mm (0.059 - 0.236in)

They are hand-held and connection to the display unit is via flexible hose and the bayonet connector.
They provide a highly accurate and quick 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.
