Model 1054B C
The Model 1054B Conductivity Analyzer measures over the range of 0-2 µS/cm to 0-1,000 mS/cm.
Temperature slope may be adjusted anywhere between 0 and 5% to provide greater accuracy in chemical con-
centration 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 1054B C will automatically calcu-
late 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.
