Equipment and materials

Abstract

The series 7458 small square‐case counter provides a compact, ½ oz counter with good figure legibility. Extensive use of precision moulded acetal resin in the construction ensures low torque and long life. Five types of drive are available — direct, revolution, ratchet, rotary ratchet and geared. They can be arranged for left or right hand shaft extension and four different mounting arrangements are available, flange, plain, panel or lug. According to drive, either 5, 6 or 7 figure models can be supplied. Normal speed is 1,000 cpm except for the direct drive model which has a speed of 5,000 cpm. Figures are white on black, 0·170 in. high by 0·087 in. wide.
