Miniature Air Plug Gauges

Miniature Air Plug Gauges are designed to be hand-held and are connected to the display unit via flexible hose.

Due to their small size they have a restricted measuring range but are ideal for measuring small precision bores.

Sizes up to 2.29mm / 0.090in are made from solid tungsten carbide as blind bore versions only. Larger sizes are made from tool steel.
