In-line Process Photometer for Concentration, Color, Turbidity & SS Measurement – Kemtrak DCP007 / NBP007 Japan Laser Corporation

Instrumentation, production technology, and quality control engineers in chemical, petroleum, pharmaceutical, food & beverage, pulp & paper, and water treatment plants; facility managers seeking in-line monitoring of process concentration, color, turbidity, and suspended solids (SS); manufacturing line managers automating and optimizing CIP/SIP cleaning cycles; IT/systems engineers integrating continuous process monitoring with DCS or SCADA systems

[DCP007] Real-time concentration and color measurement of liquids/gases directly in pipelines: petroleum products (ASTM/Saybolt color), sugar (ICUMSA color), water color, protein concentration, chlorine dioxide; quality monitoring in brewing and beverage processes; moisture measurement in organic solvents.
[NBP007] Continuous measurement of high-concentration (>1%) slurries, emulsions, and dairy product suspended solids (SS); cell/biomass density monitoring; crystallization process monitoring and control; automated CIP cleaning cycle optimization.

① One-stop coverage of concentration, color, turbidity & high-SS with two models: Combining DCP007 (transmission) and NBP007 (backscatter) covers everything from clear liquids to high-concentration slurries.
② Separated sensor/controller design = maintenance-free operation: Sensitive electronics are isolated from the process line and connected via fiber optics, eliminating signal drift in harsh temperature, pressure, and corrosive environments.
③ Dual-wavelength referencing (DCP007) for long-term stability: Simultaneous measurement and reference wavelengths automatically compensate for window fouling and light source degradation—no reagents or consumables needed.
④ High-SS measurement (NBP007): 0.001–100%: Backscatter technology handles concentrations far exceeding the ~1% limit of conventional turbidimeters, ideal for dairy, slurries, and biomass.
⑤ Traceable calibration without stopping the line: The separated design allows calibration by simply disconnecting the fiber—no process interruption or contamination.
