CM8800 Conductivity Detector

Back in 1980’s, we introduced first generation of our conductivity detector – model CM8000 that was optimized for non-suppressor ion chromatography application.

Model CM8000 and its successors have been well accepted by the world market.

New model – CM8800, which is built around the successful core technologies with solid application know-how and comprehensive industry knowledge, achieves to reduce drift (down from 3.0 nS/hour to the level less than 1.5 nS/hour) and noise (down from 0.29 nS/cm to the level less than 0.095 nS/cm).

Front panel has a dock for smartphone like user interface that is detachable from the unit for you to monitor detector reading in a remote location.
