摘　　要：Model DF-1 electrochemical analyzer is a many-purpose electrochemical instrumentation with following five functional select switches for operating conditions: cathodic /anodie polarization; single/cycle sean；two/three electrodes system；direct/derivative output；normal/differential mode. Consequently they can be combined into several working manners, result in different experimental methods as consistent with desire. This instrument has manifold compensator and adjuster with a wide-range, so that the sensitivity and the signal graph have been able to improve. In addition, the instrument incorporates a strip-chart recorder and an exact timer. It is also equipped with electrochemical bench and a set of electrodes including the rotating glassy carbon electrode, gold plate electrode, silver plate electrode, mercury coated silver base electrode, hanging mercury electrode etc. In order to broaden the field of its application, all units of the instrument can be unitized, but each and every can be also used independently. The instrument is applicable to polarography, voltammetry, potentiometric stripping, potentiostatic electrolysis,differential technique, coulometry, linear polarization method, cycle voltammetry, passivation curve, and some other electrochemical technique, which have need for electrochemical cell with two, three，or four electrodes. This paper describes the design fundament, feature and specification of the electrochemical analyzer, and finally gives laboratory application some experimental examples.Model DF-1 electrochemical analyzer is a many-purpose electrochemical instrumentation with following five functional select switches for operating conditions: cathodic /anodic polarization; single /cycle scan; two /three electrodes system; direct /derivative output; normal / differential mode.
