    For direct measurements, these indicators have a continuous dial numbered clockwise around the face. A spring-loaded plunger retracts and extends to measure objects. All have highly sensitive, wear-resistant jeweled bearings for a long service life. Rotate the dial face for viewing at multiple angles.

    These indicators come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy. They have a balanced dial with positive values on one side of the zero and negative values on the other side for comparative measurements of a part's tolerance against a reference measurement. A spring-loaded plunger retracts and extends to measure objects. All have highly sensitive, wear-resistant jeweled bearings for a long service life. Rotate the dial face for viewing at multiple angles.

    The contact point is located on the back of this indicator, which allows the dial face to be read from above. It has a continuous dial numbered clockwise around the face for direct measurements. A rugged design with few moving parts and highly sensitive, wear-resistant jeweled bearings give it a longer service life than other indicators. Rotate the dial face for viewing at multiple angles. The included tip adapter lets you use AGD-standard contact points that have 4-48 threads.

    Half of the measurement scale on the dial face is highlighted yellow to make measurements easier to read. Also known as test indicators, they have a lever-style contact point that pivots as it comes into contact with a surface and a balanced dial with positive values on one side and negative values on the other side. All have highly sensitive, wear-resistant jeweled bearings for a long service life. Rotate the dial face for viewing at multiple angles. The ratcheting contact point can be adjusted to various angles. Mount the indicator into lathe tool posts, height gauges, surface gauges, and other setups with the included accessories.

    The contact point is located on the back of this indicator, which allows the dial face to be read from above. It has a continuous dial numbered clockwise around the face for direct measurements. A rugged design with few moving parts and highly sensitive, wear-resistant jeweled bearings give it a longer service life than other indicators. Rotate the dial face for viewing at multiple angles.

    These contact points are compatible with indicators that conform to AGD standards. Most plunger indicators are classified in AGD Groups 0, 1, 2, 3, or 4.
    Radius Contact Point—Radius contact points are best for use on flat surfaces.
    Shock-Absorbing Radius Contact Point—Shock-absorbing radius contact points protect against mechanical shock. A sudden impact will cause the tip to retract into the contact point’s body.
    Button Contact Point—Button contact points are best for use on flat surfaces.
    Ball Contact Point—Ball contact points are for measuring indentations. They can also be used to measure flat surfaces.
    Bell Contact Point—Bell contact points are used for measuring convex surfaces.
    Tapered Contact Point—Tapered contact points can probe the bottom of a groove or narrow hole.
    Conical Contact Point—Conical contact points allow for precise positioning of the measuring tip. They are not for use on soft materials.

    Use the indicator in this set near magnetic chucks and other equipment with a magnetic field. The contact point is located on the back, which allows the dial face to be read from above. It has a continuous dial numbered clockwise around the face for direct measurements. A rugged design with few moving parts and highly sensitive, wear-resistant jeweled bearings give it a longer service life than other indicators. Rotate the dial face for viewing at multiple angles.
