Blinking LED Conductivity Indicator Kit

This LED (Light Emitting Diode) conductivity indicator is sensitive enough to respond to as little as 0.1 ml of liquid. It detects free H+ ions in water, and will even register low conductivity for 70% ethyl alcohol.

When both probes are in contact with a solid or immersed in a solution, and the material is a:
•Strong conductor - the LED will glow red and blink rapidly
•Weak conductor - the LED will have a steady dull glow
•Non-conductor - the LED will not light up.

The Indicator comes with a one-year limited warranty. (A 9-volt battery is required, but not included)
