An ECM (Electric Conductivity Measurement) apparatus was improved by reconstructing the current meter amplifier. The main improvements were reduction of noise and improvement of reproducibility, and adoption of a floating circuit. Further, the ECM amplifier was connected to personal computer for storage of data. Repeated measurements on the same sample indicated good reproducibility.
