Fibre Optic Process Flow Cells

The Fibre Optic Process Flow Cells (FOPFC) are developed for in-line absorbance measurements.
The Process flow cells are available with different optical path lengths and can be easily coupled to our comprehensive line of fibre optic cables and bundles through SMA connectors.
The FOPFC is consists of the sensor body, emitter focusing optics and receiver focusing optics assemblies to couple to fibre bundles with industry-standard SMA connectors, linking the process to the spectrometer.
The FOPFC has a modular design, standard process flange connections and is optimised for use in harsh environments with high temperatures and high pressures. SMA connector protection caps are available on request.
