Compact CMOS Spectrometer Accurate Measurements with 650 1 Signal-to-Noise Ratio 4ms and 200-1100 nm Spectral Range
Breakthrough UV-Vis-NIR spectroscopy meets environmental science in the SR50C. The proprietary temperature drift control (<0.01°C⁻¹) enables reliable field deployment for 24/7 nutrient monitoring, particularly effective in tracking phosphorus variations during algal bloom seasons.
The spectrometer's optical throughput (f/2.0) combined with CMOS cooling technology achieves detection limits below 10ppb for most contaminants. Municipal water authorities can now replace lab-based digestion processes with immediate in-situ measurements, significantly improving response time to pollution incidents.
