Product Overview
This handheld device indicates quantitatively the electrical conductivity of different solutions by the number of LEDs (from 1 to 10) that light up when two electrodes are immersed to a uniform depth in various solutions. This device is very simple to use - just submerge both brass prongs in a solution, hold the button on the side, and wait for the bar of LEDs to display your results. Operates on one 12-volt, type 23AE battery (NOT included).
