Claas says that there is growing demand for nutrient analysis using NIR sensor technology in grain harvesting. As a result, for the 2026 season, it has added the new Nutrimeter Grain option to make precise ingredient determination available on the Lexion combine for the first time.
Claas says the Nutrimeter Grain is the first transmissive NIR measurement system for combines that allows online measurement of grain ingredients during ongoing harvesting operations. To achieve this, it says the cuvette transmission method for stationary centres, which has proven itself in laboratory equipment, has been further developed into a continuously operating throughput method.
In contrast to the previously common reflection method, which only measures the surface of the centres, Claas notes the transmissive method measures the ingredients homogeneously through all layers of the centres.
It is fitted to the Lexion via a bypass in the grain elevator, which feeds a small amount of grain through a so-called integrating ball, in which the centre punches are completely illuminated. This allows precise measurement of the protein content in grain and the oil content in oilseeds. As a result, Claas says the sensor can be used for many types of grain.

Qualitative separation is possible during harvest
The measured values are displayed in the Cebis terminal in the cab and also transferred to the Claas connect online portal. The data documented there can be used for subsequent storage, marketing and process planning.
As the data is available during harvest in the field, different quality batches with different protein contents can, for example, be sorted specifically during unloading, transported away from the field separately and stored in sorted batches.
Claas notes that precise real-time moisture determination allows more accurate, site-specific yield recording and yield mapping. Precise live mapping is also possible on the Cemis 1200 in cab terminal, providing an initial overview of the yield potential and quality differences within an area while harvesting is still in progress – important for both farmers and contractors.
Cost
Although not committing to a price, Claas says the price for the Nutrimeter Grain is about half that of NIR devices previously available for combines. In addition to the cost of the sensor technology, there is a one-off licence fee for use on the specific machine.
