CHI200 Picoamp Booster and Faraday Cage With The Model 200 Picoamp Booster and Faraday Cage (PBFC), currents down to 1 pA can be measured. The PBFC is fully automatic and compatible with the Model 600A and 700A series (primary current channel only).When the Picoamp Booster is connected and the sensitivity scale is at or below 1e-8 A/V, the Picoamp Booster will be enabled. Otherwise it will be disabled. The instruments automatic sense whether a Picoamp Booster is connected. The enable/disable switching are also automatic. The Picoamp Booster will be disabled for techniques using automatic sensitivity switching, such as Tafel plots, bulk electrolysis (BE), and ac impedance (IMP). It is not necessary to disconnect the Picoamp Booster to run those techniques. However, for galvanostatic techniques, such as chronopotentiometry (CP) and potentiometric stripping analysis (PSA), the Picoamp Booster has to be disconnected. Besides weak signal measurements, the Faraday cage is useful to eliminate the electrical interference, especially line frequency noise. In case the electrochemical cell picks up electrical noise from the environment, the use of Faraday cage is strongly recommended. Dimension: 9.6"(W) ´ 8.8"(D) ´ 11.8"(H) Weight: 13 Lb.
