Description

For determining the electrolytic conductivity & resistance. Main features: a circular slide wire is calibrated from 0 to 10 ohms. A ratio dial with six multiple ratios of 0.1, 1, 10,100, 1k & 10k ohms is connected in series with the slide wire giving 0.01 to 100k ohms with electrolytic cell with two platinum black coated electrodes. Complete with audio oscillator and head phone.
