S430 NIR Spectrophotometer (CAT#: STEM-S-0034-LGH)

1. Wide spectral range
The instrument covers an ultra-wide wavelength range of 900-2500nm, and can detect multiple component indicators at the same time, such as moisture, fat, protein and amino acids.
2. Automatic detection
The instrument has built-in high-quality PTFE reference module, polystyrene wavelength standard plate, automatic reference calibration and wavelength monitoring, which can effectively reduce drift and provide more stable spectral data.
3. Standard integrating sphere diffuse reflection system
The instrument is equipped with a PTFE integrating sphere diffuse reflection system as standard, a large sampling spot area, and a sample rotation device, which further expands the scanning area and ensures the reproduction effect of uneven samples. It is suitable for the measurement of powder and granular samples.
4. Imported core quality
Imported tungsten lamp, optical filter, gold-plated grating, cooling type indium gallium arsenide detector, standard PTFE integrating sphere.
5. Standardized instruments
Each instrument is calibrated, identified and verified in strict accordance with industry-recommended methods, and all tests use NIST-traceable standards to ensure that every indicator of the instrument is authentic and reliable. The instruments are hardware standardized before leaving the factory, and absorbance, bandwidth and wavelength accuracy are fully controlled in the final stage of production to ensure consistency between instruments. And, once the instrument is put into use, built-in standard measurements ensure that instrument performance is drift-free over time, ensuring continuous control of consistency between instruments.
6. Extended accessories
Small sample cups for powders, large sample cups for particles, liquid reflection adapters, petri dishes and film reflection adapters can be selected to meet the testing of particles, powders, liquids and films.
7. Temperature and humidity module
The instrument monitors the ambient temperature and humidity in real time and stores it in the spectrum file, which is convenient for users to check and optimize the measurement conditions.
