This optical flange measurement cell from Hellma consists of two optics which, combined with a central part, result in a flow cell. This compact measurement cell can be safely integrated into an existing system with little effort. The materials used are resistant to organic solvents and many acids and alkalis. Instead of elastomers, the cell uses patented metal seals with a high chemical and temperature stability.
Robustness and precision are combined in one product. This guarantees a long service life and best results. Measurement cells of this category are particularly suitable for transmission measurements under harsh process conditions.
