An improved height gage is provided which includes a vertical column of rectangular cross-section, and a carriage which rides up and down the column as various heights are being measured. An electric encoder is mounted on the carriage, and it has a drive shaft in line contact with one edge of the column. The encoder supplies electric pulses to an electronic read-out circuit which, in turn, controls a display unit. The carriage is mounted on the column by means of three bearings, which are individually adjustable to establish the drive shaft in precise line contact with the edge of the column, and also to adjust the inclination of the drive shaft with respect to the horizontal for calibration purposes. The invention provides an instrument by which height measurements may be made and displayed quickly and accurately, and to a high degree of precision and resolution, on a direct basis and without the need for any calculations or other notations.
