Contactless Conductivity Detector

C2M8800 Contactless Conductivity Detector

C2M8800 Contactless Conductivity Detector is the newest member of Nichiri conductivity detector family.

Though it is a flow type detector, electrodes have no contact with solutions passing through.

An exhaustion of electrode over time, which is inevitable with traditional conductivity detector design, is minimal for C2M8800 therefore.

In food and beverage industries use pure water and ultrapure water to keep a consistent quality of products and monitor a purity of pure water and ultrapure water by conductivity detector daily basis. Conventional conductivity detector, however, requires daily maintenance to keep good reproducibility.

Long term maintenance-free operation ability is well suit for process monitoring application.

In addition to working and counter electrodes, C2M8800 has 3rd electrode (Barrier electrode so called) to prevent an influence of ambient magnetic noise.
