NIRFlex Fiber Optic Solids
The NIRFlex Fiber Optic Solids is the ideal configuration to measure solid samples in their original
container. The reflection probe operates with a fiber bundle.
The reflection probe can accommodate a transflectance adapter to analyze liquids as well (e.g.
solvents, milk, etc.).
The transflectance technique is a good compromise for customers, who only analyze liquids occasio-
nally.
The handle is equipped with a remote control for initiating the measurements remotely and displaying
the results using LEDs on the handle.
The LEDs at the handle of the fiber optic probe indicate the status of the system and the results of the
prediction in routine operation.
Applications without calibration (just measuring spectra, e.g. acquisition of calibration spectra)
- green LED flashing measuring
- green LED on measurement finished
red LED on green LED on message on monitor
Application with calibration (routine use for predictions)
- green LED flashing measuring
red LED on green LED on message on monitor
- green LED on result conforms
red LED on - result does not conform
Because the fiber optic probe is used at a certain distance from the spectrometer, the length of the
fiber optic cables between the measuring cell (spectrometer) and the probe tip is about 2 m
(3 and 5 m versions are available as well).
