Measurements are based on the latest in NIR reflectance technology for process applications including a robust sensor with a double window system.
The window into the process pipe always remains in place while the second can be removed for service work on the sensor without interruption to the process operations.
Performance validation allows you to validate ProFoss™ 2 predictions using a FOSS benchtop analyser such as NIRS™ DS3 F as reference, without any manual entry of data.
Samples are measured and registered by the ProFoss™ 2 and benchtop analyser respectively to reduce the risk of error and secure optimal performance. Using integration, connectivity and automation the results matched are saved via cloud and are ready for evaluation and reporting using digital services.
ProFoss™ 2 takes direct measurements inside the process. Sampling errors and sample preparation errors can therefore be minimized to almost zero. Monitoring process variations using a trend chart and a moving average function enables the detection of process variations of a laboratory analyser. Even if one result is wrong for some reason, this has no impact as a new result will be generated a few seconds later.
