    CHI760E series is a universal bipotentiostat, can simultaneously control both the potential of the working electrode in the same electrolytic cell, the typical application is the rotating ring-disk electrode, can also be used in other situations require double the working electrode. Bipotentiostat only be used for potential control and current measurement in the same solution two working electrodes, rather than two separate potentiostat. Instrument containing fast digital signal generator for the direct synthesis of high frequency digital signal AC impedance measurements, dual-channel high-speed data acquisition system, the potential of the current signal filter, multi-level signal gain, iR drop compensation circuit, bipotentiostat and constant current device (CHI760E). Two channels are potential range +/- 10V. Current range (two-channel currents) is 400mA. CHI760E series is the addition of a circuit board on the basis of CHI600E on the second channel containing a potential control circuit, a current - voltage converter, sensitivity selection, three gain stages, having a variable frequency range of the eight order of magnitude of second low pass filter. CHI760E able to control the potential of the two working electrodes, allowing cyclic voltammetry, linear sweep voltammetry, step wave voltammetry, chronoamperometry, differential pulse voltammetry, normal pulse voltammetry, square wave voltammetry, time - current curve and other experimental techniques to measure double the working electrode. When used as a measurement of the bi-potentiostat, the second working electrode potential can be maintained at a constant value independently, but also with a first working electrode of the scan or step-like. In cyclic voltammetry, but also maintaining the first working electrode at a constant potential difference between the scan. Current measurement two working electrodes were below the lower limit of 50pA, can be directly used to measure the steady-state current ultrafine electrodes. CHI760E series is also very fast instrument. Update rate of the signal generator is 10MHz, data acquisition using two synchronized 16 low-noise high-resolution ADC, the highest rate of dual-channel simultaneous sampling of 1MHz. Cyclic voltammetry scanning speed was 1000V / s, the potential increments only 0.1mV, when the scanning speed was 5000V / s, the potential increments of 1mV. Another example is the AC impedance measurement frequency up to 1MHz, frequency of the AC voltammetry up to 10KHz. There are instruments external signal input channels, the external input voltage signal can be recorded in the recording of the electrochemical signal at the same time, for example, the spectrum signals. This spectrum electrochemical experiment is very convenient. 
    CHI760E addition to allowing the potential of the second working electrode is independently controlled at a constant potential, but also allows the potential of the second working electrode and the first working electrode of the scan or step. When dual-channel synchronous scanning, the maximum scan rate of up to 10,000 V / s. When dual-channel synchronous step, the minimum sampling interval of up to 1 microsecond. Because CHI760E series is CHI600E series expansion, CHI760E series can also be equipped with a constant current device (CHI760E). CHI760E series also allows the four-electrode system for electrochemical measurements liquid / liquid interface. 
    When CHI760E series as a single potentiostat at the right time, the same as its performance and CHI600E series. If the connection CHI200B micro-current amplifier and shielding box, the first channel measurable 1pA or lower current. CHI760E also available and CHI680B high current amplifier is connected, resulting in a greater current and groove pressure, but only for single-channel measurements. 
    In order to meet different application needs and funding conditions, CHI760E series is divided 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. CHI760E and CHI710E basic type, CHI720E and CHI730E for integrated electrochemical analyzer, while CHI750E and CHI760E for more advanced electrochemical workstation.
