Kohlraush Conductivity Bridge Kohlraush Conductivity Bridge – Physics Laboratory Equipment Kohlraush Conductivity Bridge for direct measurement of electrolytic resistance. Kohlraush Conductivity comparing a calibrated scale 0.1 to 10 ohms and multiplier ratio dial. Giving bridge 6 ratio 0.1, 1, 10, 100, 1000, and 10000. It is useful for quick determination of resistance too when galvanometer replace the headphone in the detector circuit with fixed circular scale accuracy 1%. A circular slide wire is calibrated from 0.01 to 10 ohms A rotary dial furnishes six multipliers of 0.1, 1, 10, 100 & 1000 & 10000. Range of measurement is 0.01 to 100 K Ohm Terminals for supply and head phone/detectors are provided on the panel. A detector key is also provided. The position of slider is adjusted to the position of minimum sound or position of minimum A.C. signals. Accuracy of coils ±0.1% Accuracy of measurement ±1% at mid scale & ±2% overall.
