Universal Gage Is More Precise, More Stable, More Flexible

The Multimar 844 T has been one of the world’s most popular and proven measurement systems of its kind for decades. Now new and improved, the Multimar 844 T Universal Measurement Gage from Mahr Federal Inc. (Providence, RI) takes large ID and OD gaging to the next level. Built on a finely ground, hard chrome-plated column and available in a range of sizes, the Multimar 844 T can measure ODs and IDs up to 2,500 mm with extreme sensitivity and accuracy. These new gages now include a number of improved features that make them more precise, more stable, and more flexible than ever, including a new precision guideway with ball bearings on the moveable arm to improve reliability and repeatability. New stop elements include 3-point support for tilt measuring motion on the workpiece. New heat isolating handles reduce thermal influences, and the Multimar 844 T now comes with a set of mounting stands to hold the gage when not in use, which helps prevent damage to the gage.

The Multimar 844 T can be fitted with any measuring indicator with an 8 mm mounting shank, including new wireless indicators for easy data collection with no cables. The stationary measuring arm can be moved along the column for coarse adjustment, and constant measuring force is applied due to a built-in measuring force spring. Both the direction of the measuring force and the measuring arms can easily be changed for either external or internal dimensions. Gages larger than 1,000 mm (39.75 in) incorporate a carbon fiber reinforced plastic tube to lighten the gage without losing stability.

The Multimar 844 T is a very versatile and flexible instrument for measuring IDs and ODs; external and internal thread measurements; centering shoulders, narrow collars, recesses and grooves; external and internal tapers; external and internal gear tooth profiles; and more. Its tubular shape and robust construction make this gage very easy to use. What makes the Multimar 844 T so versatile is the wide range of measuring arms, anvils, mounting attachments and depth stops available. Anvils and tips are available in a wide variety of shapes and configurations, including threads, flat and spherical shoulders, blades and round faces. Depth stops can be set to the exact measuring depth in the horizontal measurement position to provide precise support on the reference plane surface. This improves repetitive accuracy when conducting comparison measurements in the second axis, and when used with a rectangular gage block, can provide accurate depth measurement on cones.

These gages are available in seven models for different ID/OD size ranges and are supplied with battery, instruction manual, mounting and resting blocks, and a finely crafted wooden case.
