scale expansion from 0.3 X to 50 X in concentration mode, peak readout system measures peak absorbance — this feature is especially useful for short-duration signals such as those encountered with the carbon The Models 1200 (digital readout) rod atomizer. and 1100 (meter readout) are choice of two integration simple, c o m p a c t and ideal for periods (3 or 10 seconds); high volume routine analyses. integrated results can be displayed indefinitely. Other features include: curvature correction permits readout: Model 1100 has direct linear readout in 10 cm clear, open scale concentration units over the entire meter giving linear presentation; 0-2.0 absorbance range. Model 1200 has four digit readout automatic zero adjustment up to 9999. corrects for baseline drift. I n t e g r a t i o n , a feature in the latest Varian Techtron atomic absorption spectrophotometers, Models 1100/1200, provides precise, unambiguous readout of data and eliminates operator error.
