ABSTRACT:
A portable precision indicator gage for measuring the distance between two contact points. The portable gage is adapted to receive an indicator device for indicating a dimension of an object corresponding to a distance between two contact points having a movable indicator pin defining one of the contact points. The portable gage has a tubular housing including a radial surface having a port for facilitating viewing of an indicator device and a proximal end portion, and spaced axially therefrom a distal end portion. An end cap is connected to the proximal end portion having an end port adapted to receive a movable indicator pin therethrough, including an anchor pin extending outwardly therefrom. The movable indicator pin and the anchor pin define a first and a second contact point, respectively. And, an adjustment mechanism is provided for adjusting the distance between the contact points, and is connected to the housing.
