Description
Technical field
The technical program relates to the potential electrode of electrical conductivity of solution or resistivity, particularly relates to the electrical conductivity of solution or resistivity measurement electrode that can eliminate electrode polarization completely.
Background technology
The measurement of liquid electric conductivity widely uses in the numerous areas such as commercial production, water quality monitoring.The fundamental method of measurement of electrical conductivity of solution measures the voltage U be applied on the two ends of the electrode of inserting solution and the electric current I flowing through electrode, and calculate the resistance R=U/I between electrode, calculate the conductivity of solution with G=K/R, wherein K is electrode constant.But the electrode of inserting in solution can produce polarization after powered up, the voltage U recorded is made not to be in fact the voltage at the two ends of solution own, but the voltage be applied on solution resistance series connection electrode polarization equivalent capacity two virtual electronic devices, therefore there is theoretical error in formula R=U/I; In order to reduce the impact of electrode polarization on accuracy of measurement, basic skills is that alternating current such as the sine wave applying positive-negative polarity symmetry on electrode encourages, but ac-excited method just can reduce electrode polarization impact, can not eliminate the impact of electrode polarization completely, and ac-excited electrode interelectrode capacity and the contact conductor electric capacity sum can introduced is on the impact of measuring.
Summary of the invention
The object of the technical program is to provide a kind of liquid conductivity measurement electrode eliminating electrode polarization completely.
The technical scheme realizing above-mentioned purpose is: a kind of liquid conductivity measurement electrode with micro pump, is made up of two electrodes i.e. the first electrode, the second electrode and micro pump; Two electrodes i.e. the first electrode, the second electrode is the cylindrical straight tube that the unequal height of diameter is equal, and the first electrode is the cylindrical straight tube having bottom surface, and the second electrode is the cylindrical straight tube without bottom surface; Second electrode and end face coaxial with the first electrode aligns and installs, form two alignment electrode end surfaces, that end face that wherein corresponding first electrode has a bottom surface is called the first alignment electrode end surface, other end is called the second alignment electrode end surface, second electrodes surrounding first electrode, leave uniform gap between the cylindrical side wall of two electrodes, the first alignment electrode end surface coaxially connects with the water side of micro pump.
The innovative point of the technical program is: the micro pump liquid opened in rear conductance cell flows fast through the gap between the cylindrical side wall of two electrodes via micro pump circulation, continuous fast flush electrode surface, make electrode surface can not assemble and adhere to ion and form firm electrostatic double layer, also namely avoid electrode polarization.
