Series 300 Transmission Probe

The Series 300 probe enables remote near-IR measurements of heated and pressurized clear to slightly scattering liquid process streams. To perform this measurement two probes are required; one for transmitting the radiant energy and the other for collecting. These probes use an optically efficient radius sapphire window to perform high transmission of a collimated beam. Removable pre-set fixed path length spacers are available as an option.

Probe variations, but are not limited to:

Series 325 Extruder Type Single Fiber Transmission

Series 350 Extruder Type Micro Bundle Transmission

Series 400 Diffuse Reflectance Probe

The Series 400 probe allows remote spectroscopic measurement of highly scattering material. This probe uses a special, optically designed sapphire window concentrator along with the unique bundling of the fibers that optimize the collection efficiency while virtually eliminating undesirable background noise.

Probe variations, but are not limited to:

Series 410 Purge Diffuse Reflectance

Series 450 Extruder Type Diffuse Reflectance 

Series 470 Non Contact Diffuse Reflectance 

Series 500 Single Pass Transmission Probes

The Series 500 probe enables remote near-IR measurement of heated and pressurized clear or translucent liquid process streams. The innovative optical arrangement of the probe provides a true single pass transmission design with superior quantitative performance. The probe can easily be connected to two 600 micron single fiber assemblies. An internal purge capability as well as variable path length configurations are available

Series 600 Transflectance Probes

The Series 600 provides remote spectroscopic transmission measurement of heated and pressurized clear or slightly scattering liquid process streams. The probe contains two internal 600 micron fibers or an integral bifurcated micro fiber assembly. Interchangeable fixed and variable path length mirror tips are available. This is a double-pass design, which makes the effective path length twice the physical gap. A special probe configuration can also be provided that combines the capability of both transflectance as well as diffuse reflectance measurement. 

Probe variations, but are not limited to:

Series 625 Single Fiber Transflectance Probe

Series 650 Transflectance Probe

Series 700 Flow-Through Transmission Cell

The Series 700 cell is fiber coupled for unattended side-stream or in-line monitoring of heated and pressurized liquid process streams or gas mediums. The cell consists of two optically efficient sapphire windows that create a wide collimated beam across the interior of the cell. Options include precision spacers to adjust path length, channels for fluid temperature control, temperature sensor and clean out port.
