Corona Extreme
The Zeiss NIR for Agriculture
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.
