This specialized version of the PrepFlowCell 3/4 inch combines robust inline process analysis with the flexibility of a manual reference measurement. Thanks to the integrated cell holder, this system enables direct validation of the inline measurement data directly on the process flow.
The attached cuvette holder offers decisive advantages for quality assurance and process control:
Direct validation & adjustment: Enables immediate comparison of the inline measurement values with a manually drawn sample in a standard cuvette (reference measurement) without having to convert the system.
Simple calibration: Reference standards or calibration solutions can be easily inserted into the beam path to verify the sensors during operation.
Increased process reliability: Fast verification of limit value violations through offline measurement in the same optical setup.
Flexibility in laboratory and pilot plant applications: The cell can be used both for continuous flow and as a stationary measuring unit for individual samples.
Material: High-quality stainless steel (1.4404 / 316L) for maximum mechanical stability.
Integrated holder: Holder for standard 10 mm cuvettes (or sample carriers).
FiberSeal technology: Secure sealing of optical components.
Inline measurement: Optimized for high flow rates with minimal dead volume.
Precision: Outstanding path length accuracy (< ±0.03 mm).
Connections: SMA 905 with Fiber Guard to protect the fiber optic cable.
