9 Level Conductivity Indicator Tester

The Nine Level Conductivity Meter accurately displays the relative conductivity/resistance of various liquids and solids. As the conductivity of the tested material increases, up to 8 glowing red LEDs will illuminate, indicating excellent conductivity. Conversely, if the material has low electrical conductivity, no LEDs will glow, suggesting good insulation properties. This well-constructed meter, when handled with care, ensures prolonged exemplary performance. It is essential to clean and dry the probes after each use and remove the 9V battery when storing, as a 1.9V battery is required but not included.
