Brief introduction: JP - 06 type a precision polarographic analyzer USES the on-chip system with advanced technology, in a highly integrated, at the same time significantly improve the sensitivity and reliability of the polarographic system, the machine power consumption is less than 10 w. Instrument with USB interface, can be easily connected to the PC and computer workstation platform, effectively exert a powerful computer calculation and processing capacity. JP - 06 type a precision polarographic analyzer with ultra low impedance full electronic switches and hardware compensation, broadening the scope of effective current measurements to 1 x 1 x 10-10-3 a ~ 9 a (f. S), improve the quality of the signal. Instruments have a combination of free dropping mercury detection circuit, can accurately detect dropping mercury free time, automatically determine the best scanning start time, greatly convenient for use and maintenance of the instrument. At the same time, the instrument adopts the high resolution digital to analog and analog acquisition unit, 24 bit AD converter and low drift program-controlled amplifier circuit can effectively distinguish as low as 1 uv signal, combined with internal first derivative and second derivative instrument circuit, can distinguish the very weak electric current signals, the related research has important significance.
