GE AKTA pH/C-900 Monitor
The GE AKTA pH/C-900 Monitor is a combined unit for accurate, on-line monitoring of pH and conductivity in a wide range of liquid chromatography applications. Monitor pH/C-900 precisely measures the elution conditions of chromatographic separations, either as a component of ÄKTAdesign systems or as a standalone instrument. It displays pH, conductivity, and temperature. Since temperature can influence both pH and conductivity, the monitor compensates for temperature variations of these readings. Self-diagnostics ensure continual reliability and reproducibility. Both the pH and the conductivity/temperature flow cells feature low cell volume and high linearity for accurate measurements.PH Electrode Not Included.
The GE AKTA pH/C-900 Monitor includes:
- > Conductivity Sensor
- > Power Cord
- > Full 180 Day Parts and Labor Warranty
