SEC1106 Series Electrochemical Workstation

SEC1106 series electrochemical workstation is a new generation launched by Saluki which is providing an accurate measurement platform for researchers involved in life science, sensor, corrosion, physical electrochemistry, environmental protection, batteries, materials, and other fields.

SEC1106 series adopts a potentiostat with full digital feedback. The EIS operating frequency is up to 3MHz, and the basic measurement error is within 0.1% (in the impedance range greater than 100kΩ, the test error is less than 1%). Three independent acquisition links, combined with adaptive filtering and amplification technology, adopt 16-bit, 10MSPS high-performance ADC so that the measurement results have ultra-high sensitivity and accuracy.

    Constant current charge and discharge method (CCD) also known as chronopotentiometry. Its specific principle is to charge and discharge the tested electrode under constant current conditions, record the variation law of its potential with time, and then study the charge and discharge performance of the electrode to calculate its actual specific capacity.


    CCD can determine the charge-discharge curve, capacity, rate characteristics, cycle performance and other parameters of electrode materials. It is best to test in a relatively constant temperature environment, and cycle charge and discharge many times to obtain stable data.
