This is a next-generation, quality-improving liquid
concentration monitor. • Compact design enabling layout flexibility   Compared to the previous model (CS-100F1 Series), the unit height has been reduced by
  36%, overall volume by 40%, and the required space for the cell section by 46%, achieving
  a compact design. In addition, the light source unit and monitor main unit can be installed
  separately, allowing flexible layout configuration to suit the available space of chemical
  supply units or cleaning equipment.
• Stable direct measurement of high-temperature chemicals (20–80 °C)   Through an enhanced optical system and advanced data processing algorithms, direct
  measurement of high-temperature chemicals required for advanced wet processes is
  achieved. This enables stable concentration measurement without fluctuation, even during
  direct high-temperature operation, eliminating the need for chemical cooling.
• Significantly reduced background calibration frequency in in-line measurement   Compared to the previous model (CS-100F1 Series), the frequency of periodic calibration
  has been greatly reduced, minimizing equipment downtime and contributing to
  improved throughput.
• Measurement of up to six chemical types with a single unit   A single monitor supports measurement of up to six different chemicals or measurement
  ranges, providing flexible configuration to meet a wide variety of measurement
  requirements.
• Built-in data logging function   A real-time data storage function—unavailable in the previous model (CS-100F1 Series)
  —has been newly implemented. In the event of any system event, stored internal data can be
   immediately backed up and analyzed, enabling prompt and effective service response.
