NIR spectrophotometer SP-NIR450

tungstenreflectancesphere

Description
SP-NIR450 NIR SPECTROMETER is a next-generation raster-scanning near‑infrared (NIR) spectrometer developed from previous models with upgraded hardware and software to deliver faster, more accurate and stable measurements. It is designed for precise analysis of agricultural, food, tobacco, pharmaceutical and industrial samples using diffuse-reflection sampling.

Key performance

• Wide spectral range covering 900–2500 nm (11000–4000 cm-1)
• Automatic detection and standardized operation
• Integrating-sphere diffuse-reflection sampling system for uneven samples
• High-quality imported core components (tungsten lamp, gratings, refrigerated InGaAs detector)
• Instrument standardization enabling reliable inter-instrument model transfer
• Extended accessory options for powders, liquids, films and particulates
• Real-time ambient temperature and humidity monitoring

Features

• Simple operation with no sample preparation and non-destructive measurement
• Covers 900–2500 nm for broad NIR applications
• Core components use internationally recognized brands to ensure stability and performance
• Multiple traceable wavelength calibration standards with evenly distributed calibration points
• Integrating-sphere collects diffuse reflectance at multiple angles to improve reproducibility on uneven samples
• Consistent performance and manufacturing support effective model transfer and reduce calibration deployment costs
• Various sample cups and accessories available for particle, powder, liquid and film testing
• Records ambient temperature and humidity in spectrum files to support result traceability
• Software is user-friendly; spectrum files compatible with analysis packages such as Unscrambler
