More Information
Summary:Disclosed is a polarographic densitometer, comprising: a voltage applying circuit; a sensor unit; an impedance reduction circuit; and a current/density conversion unit. According to the present invention, said voltage applying circuit applies specified voltage, and said sensor unit includes a group of electrodes to produce a current output in response to any reaction caused in a specimen when the specified voltage is applied by said voltage applying circuit. Furthermore, said impedance reduction circuit reduces impedance of the specimen between said electrodes of the group, and said current/density conversion unit converts the current output of said sensor unit when the impedance is reduced by said impedance reduction circuit into the density of specific material in the specimen.
