Excellent results, easy to use, convenient
Application Area: It is a general proposed electrochemical measurement instrument
"Its to easy to use because it doesn't use any plugin cord or hardware to connect and it also avoid the periodic racallibration of the instrument by resetting potential and current zero "

Excellent product!
Application Area:Electrochemical detection
"In general the product is very good. It cost a very low price and it works super well. "
The steady state current of a 10 mm disk electrode can be readily measured without external adapters. With the CHI200B Picoamp Booster and Faraday Cage (fully automatic and compatible with the CHI600D series), currents down to 1 pA can be measured. These instruments are very fast. The function generator can update at a 10 MHz rate, and the maximum sampling rate is 1 MHz at 16-bit resolution. The instrument provides very wide dynamic range on experimental time scales. For instance, the scan rate in cyclic voltammetry can be up to 1000 V/s with a 0.1 mV potential increment or 5000 V/s with a 1 mV potential increment.
The potentiostat/galvanostat uses a 4-electrode configuration, allowing it to be used for liquid/liquid interface measurements and eliminating the effect of contacting resistance of connectors and relays for high current measurements. Multiple data acquisition systems allow an external input signal (such as spectroscopy signals to be recorded simultaneously with electrochemical data). The instrument will also automatically re-zero both potential and current, so that periodic re-calibration of the instrument can be avoided.
