The PTRam is a compact, sensitive, and robust Raman spectrometer that can be placed on the bench or in a rack-mount enclosure. Just connect the fiber optic probe, plug it in and start your measurements, easily moving it to the process you are developing. With the PTRam you can increase your process understanding and decrease development time with real-time process monitoring.

In addition, the PTRam is a stable system, with high repeatability and reproducibility. It includes internal monitoring of system temperature and Raman shift, ensuring precise measurements throughout your analysis.

Regular control of process parameters is critical to maintain product and process specifications and to achieve optimal product quality and consistency in any industry. By providing data in «real-time» to the industrial control system (e.g. DCS or PLC), downtimes are reduced, and costly company assets are safeguarded.

The 2060 Human Interface developed by Metrohm Process Analytics helps you to achieve that. Thanks to the variety of process communication protocols built-in with the 2060 HI (e.g., Modbus or Discrete I/O), process data can be communicated in «real-time» to any industrial control system or directly to external devices and is accessible 24/7.
