Conductivity Meter, Each

Details

Testing The Conductivity Of Solutions Can Give Important Insights Into The Nature Of, And The Particles In, A Solution. This Conductivity Meter Uses A Green And A Red Light Emitting Diode (Led) To Quantitatively Measure The Conductivity Of A Solution. The Green Led Requires More Voltage Than The Red Led. Immersing The Electrodes Into A Weakly Electrolytic Solution Results In A Dim Glowing Of The Red Led While The Green Led Remains Off.
