Corona Extreme
the Zeiss NIR for Agriculture
Read More Below
Corona extreme and InProcess® software is the spectrometer system designed to increase productivity in agriculture analysis. The idea was to create a measuring sensor, which is a key component of the process in extreme conditions for the entire product life cycle. With the ZEISS competence in hardware, software and engineering this resilient and precise system can withstand extreme workloads and is considerably superior to lab measurements.
Corona extreme is designed based on much application-related experience and provides reliable measurement results for each sample. The compact system is easy to install and can be operated independently using the embedded controller, which enables a direct evaluation and output of the predicted data without the use of a computer. The spectrometer features fibre free, high-energy illumination with outstanding optical properties and internal referencing.
