CompactSpec II: Process UV-VIS-NIR Spectrometer System

CompactSpec II and CompactSpec II EEx are fast
and robust UV-VIS-NIR spectrometer systems in a
stainless steel cabinet (IP54) with an industrial PC
and TFT touch screen monitor. Based on fast and
reliable detector array and highly stable lamp
technology, it is optimized for demanding process
applications. Real multi-channel operation can be

realized by diverse multiplexer options. The system
is available with various spectral ranges and resolutions. Fiber optics in combination with probes or
flow-through cells allow measurements in pipes
and reactors, close to the line.

CompactSpec II
Multiplexing – Multi Channel Systems
The electronic spectral sensor multiplexer MUX-8A (for
Si-PDAs) provides important advantages. For multi-point
applications, spectra of up to 8 channels can be taken
simultaneously therefore, the costs per measurement point
is reduced dramatically. Variations and drifts of the light
source are compensated perfectly by using 1 channel as
reference channel. The tec5 multiplexer has no moving
parts and is fast and reliable.
For NIR applications an optical multiplexer based on piezo
technology is available. Fast switching time, low coupling
looses, very good reproducibility and a high lifetime are
characteristic of this unit.
