LED Conductivity Indicator

(in stock)


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. The LED Conductivity Indicator requires no special preparation. Its safety and ease of operation will increase your students’ understanding by creating a "hands-on" experience. Requires a 9-V battery for operation (not included).
