Purpose and areas of usage
10 - channel device is designed to measure the parameters of super - capacitors in different measuring modes:
- galvanostatic 1 - charge / discharge with direct current;
- galvanostatic 2 - with disconnection of current at reaching the final given voltage values;
- galvanostatic 3 - sequence of charges with the disconnection of current after each charge and at the end of discharge;
- combined - galvanostatic and potentiostatic, which combines charge / discharge with direct current and support of the final given voltages.
The device is used in the laboratories of enterprises and research institutes in the field of instrument making.
Main characteristics, gist of development
The main functions of the device are regulation (support) of the given potential of the investigated (working) electrode in the potentiodynamic mode or regulation (support) of the given polarization current in the circle of the studied (working) electrode in the galvanostatic and combined modes irrespective of the processes occurring in the electrochemical cell.
The regulation of the potential of the working electrode is carried out by automatic measurement of the polarizing (output) current of the stand.
The regulation of the polarization current in the circle of the working electrode is carried out by automatically changing the output voltage of the stand.
The number of measuring channels is 10.
The voltage range is 0 to + 3. 5 volts.
Current setting range - + 100 A.
Current measurement error 0. 5% .
Error of measurement of voltage - 0, 5% .
The minimum reading time of the voltage and current of the stand in each channel is 10 ms.
10 - channel device designed to measure the parameters of super - capacitors, successfully used in LLC "UNESCO - Ukraine".
