The simplest output devices consist of a moving–coil meter or a pen recorder displaying percentage transmission (%T). The Model 460 has a digital display, which provides a direct readout of absorbance values. This, with a provision for curve linearization, forms the basis for displaying outputs directly in concentration terms, using standard solutions for calibrations. At present, most aspects of instrument control, operation, standardization and data processing or storage are carried out by a microcomputer or microprocessor built in into the atomic absorption or interfaced to it.
