Digital length gage measures precise lengths to three decimal places in lengths up to 4 meters long.  It is excellent for industrial and commercial applications that require precise length measurements of aluminum and plastic extrusions, tube, pipe and hose.  The operator can program the display to show inches or millimeters.  The length measurement gage is available for up to 12-foot (4-meter) lengths, in one foot increments.  One, two, three, and four-meter lengths are standard.
