Slope Meter SCSI - Safe Curve Speed Indicator Slopemeter - SM_SCSI

The safe driving speed for any curve is quickly and accurately determined with the "SCSI" mounted in the engineer's car.  The scale reads zero when the car is level, and will show "tilt" up to 25 degrees on each side.  The scale is red beyond +/-10 degrees to denote danger zones.  The "SCSI" was designed by Slope-Meter in accordance with the specifications of the Minnesota Highway Dept.  Traffic Division and is used nation-wide by highway and traffic engineers.
