BROWN ELECTRONIKS WE P R E D I C T that these five measuring elements presage a phenomenal change in process control techniques during the next decade. The direct, continuous measurement and control of chemical composition will replace many of the inferential methods now in use. Analysis and measurement which formerly took days or hours of extremely skilled work has been reduced to minutes of routine procedure. The Brown ElectroniK Potentiometer has been responsible for moving laboratory techniques into the plant. Greater accuracy, sensitivity and speed of response has made it a leader in the fields of chemical analysis and composition control. THE POLAROGRAPH

The Polarograph is an analytical instrument, both qualitative and quantitative, for determining the chemical constituents of either aqueous or nonaqueous solutions. Both in micro and macro analytical work, the Polarograph replaces tedious and slow wet chemical methods. The high speed of the Brown ElectroniK recorder facilitates obtaining a well defined analysis curve. T H E GEIGER-COUNTER X-RAY SPECTROMETER Until recently, the time and technique required to perform and evaluate an analysis have limited the usefulness of an X-ray Spectrometer. Elimination of these two barriers is principally the result of two achievements in electronics: (1) The Geiger-Muller Tube, and (2) the Brown "Continuous Balance" High Speed Recording Potentiometer. Only ninety minutes are required to obtain a complete diffraction pattern with this high speed combination. The fast pen speed of 4}^ seconds across scale combined with the high chart speed of 120 inches per hour make it possible to spread out the record, contributing to convenience and accuracy in analyzing diffraction patterns.
