Polytec NIR Spectrometers - Compact, versatile & flexible

Measure liquid, solid, and pasty material with one system

Measure liquid, solid, and pasty material with one system

Polytec’s spectrometer system is uniquely capable of measuring liquids, solids, and pasty materials with a single device, offering unmatched versatility for different industrial applications. Whether analyzing viscous liquids like oils, dry powders, or mixed consistency materials such as pastes, this all-in-one solution provides a seamless transition between various sample types. This capability is particularly beneficial for industries like food processing, agriculture, and pharmaceuticals, where diverse sample materials require precise and consistent analysis without the need for multiple instruments or setups.

Smallest dust-explosive proof sensors

Smallest dust-explosive proof sensors

Polytec's dust-explosive proof sensors, the smallest in their class, come with certifications for multiple countries, ensuring compliance with diverse safety regulations worldwide. These sensors are designed to be safely used in potentially hazardous environments where dust explosions are a concern, such as in milling, mining, starch, and other industries where powder is involved. The compact design allows for easy integration into existing systems, providing robust safety and high-performance analytics in dusty conditions. This makes Polytec's sensors a reliable choice for industries needing to comply with strict safety standards without compromising efficiency.

working principle of multiplexers in industrial environments

Multiplexer - monitor multiple production steps

Multiplexer - monitor multiple production steps

Polytec's NIR spectrometers can be equipped with up to 6 probes thanks to the multiplexer technology. This allows the producer to use only one spectrometer to monitor multiple production steps. 

The Multiplexer enables efficient spectrometer-based analysis at multiple measurement points within a process, allowing for flexible integration with various probes. This setup is ideal for performing multiple evaluations simultaneously, reducing costs, and optimizing the efficiency of the measurement process. The multiplexer can handle multiple channels, making it versatile for different types of analyses across several stages of a production line. This capability is particularly useful for industries that require comprehensive monitoring and data collection throughout the production process.

Contact sensor head for short distances

The most compact sensors for short and long distances

The most compact sensors for short and long distances

Polytec's sensors are compact and easy to install, making them ideal for flexible use in industrial settings. The PSS-H-B01 and PSS-H-B02 contact sensor heads are designed for close-range sample measurements, handling liquids, powders, and bulk materials at distances up to 50 mm. For longer distances, the PSS-H-A03 distance sensor head allows measurements from 150 to 600 mm, perfect for conveyor belts and strip products. Both sensor types feature robust construction for demanding environments, providing versatile options for accurate process monitoring.

Process Analytics

Two wavelengths (2100 nm wavelength range)

Two wavelengths (2100 nm wavelength range)

Polytec's spectrometer system offers two wavelength options, with the 2100 nm wavelength being particularly advantageous for analyzing edible oils. This wavelength is highly effective for measuring oil characteristics, making it ideal for applications across various oil types. The ability to utilize this specific wavelength ensures precise and reliable analysis, which is critical for quality control in food production.

Analyzing ingredients and optimizing processes

Process analytics is used to optimize the production process, to ensure consistent product quality and, last but not least, to meet environmental requirements. The objective in this regard is to improve product quality and enhance efficiency with a view to reducing costs, saving time and cutting emissions. Automated real-time control allows for controlled interventions to be made even during the product manufacturing process. Costly and time-consuming faulty production operations are prevented as a result.

Process analytics can be used throughout the entire production chain: when inspecting incoming goods, during production (either online in the form of automatic sampling while bypassing process control, or inline in the form of automatic sampling directly during process control) and during final product control.

As they are easy to use and robust, spectroscopic methods – particularly near-infrared (NIR) spectroscopy based on dispersive diode array technology – are a popular choice in this area of application.

The available measured variables are diverse in this regard:

  • Qualitative and quantitative compositional analyses to determine the concentration of products, additives and by-products, and to identify process-specific substances
  • Physical parameters in both the reactor and the reaction mixture, such as the humidity level
