Lab-Aids®. This conductivity indicator measures relative electrical conductivity of a liquid or solid by a light emitting diode (LED) display. A good conductor is indicated by a continuous "blinking" of the LED, a weak conductor is indicated by a dull red "glow" of the LED, and a poor or non-conductor will not cause the LED to glow or blink.
