Two systems - one goal: optimal process control.
Polytec offers two powerful inline NIR spectrometer systems: the PAS (Polytec Advanced Spectrometer) and the PCS (Polytec Compact Spectrometer).
- The PAS system provides maximum flexibility and is ideal for complex, multi-point measurement environments.
- The PCS, on the other hand, is designed for easy integration, offering a compact footprint, high-speed measurements, and excellent cost efficiency.
Both systems ensure real-time, accurate analysis of critical process parameters – helping you improve efficiency, consistency, and product quality.

The benefits of Polytec NIR spectrometers:
- Real-time quality control directly in your production
- Increased efficiency through optimized processes and reduced waste
- Flexible application across various industries (e.g. food, recycling)
- Easy operation thanks to user-friendly software solutions
- Maximum process reliability through consistent, in-process measurement
- Quick return on investment due to efficiency gains and lower operating costs
