The Slope meter Safe Curve Speed Indicator (SCSI)
The Safe Curve Speed Indicator (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 SCSI was designed by Slope-Meter in accordance with the specifications of the Minnesota Highway Dept. Traffic Division and is used nation-wide (USA) by highway and traffic engineers.
