ABSTRACT:
Methods and apparatus are disclosed herein for measuring the electrical conductivity of unknown fluid solutions. A constant current DC pulse having a very fast rise time is supplied to a test cell containing the unknown solution. By sampling the voltage across the test cell just prior to the application of the pulse and at a predetermined time during the application of the constant current pulse, a voltage difference is obtained which may be interpreted in terms of the conductivity of the unknown solution.
