    CHI660E series for Universal electrochemical measurement system. Containing fast digital signal generator, high-speed data acquisition system, the potential current signal filter, multi-level signal gain, iR drop compensation circuit, and potentiostat / galvanostat (E). Potential range of ± 10V, current range of ± 250mA. Current measurement limit lower than 50pA. Steady-state current measurements can be used directly on ultramicroelectrode. If the connection CHI200 micro-current amplifier and a shielding box, measurable 1pA or lower current. If high-current amplifier is connected with CHI680 current range can be widened to ± 2A. CHI660E series is also very fast instrument.
    Update rate of the signal generator to 10MHz, data acquisition using two synchronized 16 low-noise high-resolution ADC, the highest rate of dual-channel simultaneous sampling of 1MHz. Dual-channel synchronous current potential sampling can accelerate the speed of the impedance measurement. Some experimental methods timescales up to ten orders of magnitude, the dynamic range is extremely broad. Scan speed cyclic voltammetry of 1000V / s, the potential increment only 0.1mV, when the scanning speed of 5000V / s, potential increments of 1mV.
    Another example is the AC impedance measurement frequency up to 1MHz, the frequency of the AC voltammetry up to 10KHz. Instrument can work in two, three, or four-way electrodes. Four electrodes can be used for liquid / liquid interface electrochemical measurements, for large currents or low-impedance electrolytic cell (such as batteries) is also very important to eliminate measurement errors due to cable and contact resistance caused. Instruments as well as external signal input channel, simultaneous sampling of up to 16 high-resolution rate of 1MHz. Recording the electrochemical signal can be recorded while the external input voltage signal, such as spectral signals. This spectrum is very convenient electrochemical experiments.
    CHI660E Series hardware using a high-speed processor, fast amplifiers, fast ADC and DAC. Chronocoulometry plus analog integrator. A 16 high-resolution stable current bias circuit to achieve a current-zero output, can also be used to improve the measurement of AC current dynamic range. High-resolution ADC has a better signal to noise ratio, but also gives a greater dynamic range of sensitivity settings.
    CHI660E series instruments internal control procedures using FLASH memory. Instrument software updates no longer need to post and replace EPROM, which can be transmitted through the network and through the program command is written. This allows software updates faster and easier.
    CHI660E series also allows upgrades for bipotentiostat. The new design of the second channel by adding a potential control, the current-voltage conversion gain, and a multi-stage low-pass filter circuit board, has become CHI760E series bipotentiostat.
    CHI660E Series instruments integrates almost all commonly used electrochemical measurement techniques. In order to meet different application needs and funding conditions, CHI660E series into a variety of models. Different models have different electrochemical measurement techniques and features, but the basic parameters of the hardware and software performance indicators are the same. CHI600E and CHI610E basic type, respectively, for the mechanism of research and analysis applications. They are also very good teaching instrument. CHI602E and CHI604E can be used for corrosion studies. CHI620E and CHI630E integrated electrochemical analyzer, while CHI650E and CHI660E for more advanced electrochemical workstation.
