CS-100 Series

CS-100 Series

Stand-alone Type Chemical Concentration Monitor


The CS-100 Series offers a complete lineup of high precision chemical solution concentration monitors for various solutions in cleaning and etching processes during semiconductor manufacturing. In addition to the high-speed response and compact design, measurement of each component concentration is conducted in real-time and the timing of chemical solution changes and automatic supply is warned with an alarm. The ability to perform short measurement cycles allows for accurate monitoring of concentration changes.
