For Your Information
The new AD-2Z Autobalance with both Autoranging and Autozero It can set zero, balance the beam, select the best range, shift the decimal, display the weight on a large digital readout, print it (with an optional printer) and much more . . . all automatically and within seconds. That's what all microbalances should do, but only the AD-2Z does. 5 gram capacity, 0.1 microgram sensitivity. Recording and vacuum models available.

T h e industrial microcomputer market in the U.S. will grow more t h a n twentyfold over the next 10 years, according to the study released by the New York City-based research specialists, Frost & Sullivan, Inc. T h e study predicts that shipments of in dustrial microcomputer equipment will soar from $45 million in 1975 to $1.2 billion by 1985. This tremendous growth in the sales of industrial micro computers is attributed to its cost ef fectiveness. For example, in the pro cess control industry, on-line control of sophisticated instruments and data handling can be achieved with micro computers a t a greatly reduced cost. T h e study predicts t h a t among end users the chemical industry will com prise the largest single industrial mar ket by 1985. Here, in addition to their use in measuring instruments, micro-
