The Model 1054A Conductivity Analyzer measures over the range of 0-2 µS/cm to 0-1,000 mS/cm. Temperature slope may be adjusted any-
where between 0 and 5% to provide greater accuracy in chemical concentration control. The temperature slope is factory set at 2% as a representative value, but each conductive solution has its own set of temperature vs. concentration curves. The Model 1054A C will automatically calculate the temperature slope for any given solution, or permit manual adjustment of the temperature slope if already known. On calibration the analyzer will also automatically correct for cell constant variations for better measurement accuracy.
