Conductivity Indicator Tester
Nine level conductivity meter shows the relative conductivity/resistance of liquids and solids. As the conductivity of the tested material increases, the number of glowing red LEDs will increase to a maximum of 8, which indicates a very good conductor. There will be zero glowing red LEDs if the material has a very low electrical conductivity (is a good insulator).
