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).

The nine level conductivity meter is well constructed. When treated with proper care and concern it shoul provide you with many hours of exemplary service. After each use, the probes should be thoroughly cleaned and dried. When storing, the 9 V battery should be unsnapped from the battery posts.

Informations de commande: 1.9 V battery is required, but is not included.
