    Journal: Rev Sci Instrum; 2009 Aug; 80(8):084101. PubMed ID: 19725669.
    Abstract:
    The virtual ion meter is developed based on LABVIEW 8.0 by homemade adjusting circuit, data acquisition (DAQ) board, and computer. This note provides details of the structure of testing system and flow chart of DAQ program. This virtual instrument system is applied to multitask testing such as determining rate constant of second-order reaction by pX, pX potentiometric titration, determining oscillating reaction by potential, etc. The result of application indicates that this test system not only has function of real-time data acquiring, displaying, storage, but also realizes remote monitoring and controlling test-control spots through internet, automatic analyzing and processing of data, reporting of result according to the different testing task; moreover, the veracity and repeatability of data processing result are higher than the results of manual data processing.
