electrical signals and these signals will be amplified and processed.The number and diameter of particles can be obtained by analysis because the signal waveform has certain relations with the particles diameter. \u003cspan style=\"font-size:16px;\"\u003e\u003cstrong\u003eTechnical Parameters:\u003c\/strong\u003e\u003c\/span\u003e \u003c\/span\u003e\u003ctable
