Electric Digital Spectrophotometer, Certification : ISO9001:2008

Spectrophotometer specifications define its performance capabilities and components, including wavelength range (e.g., 190–1100 nm for UV-Vis), photometric range (Absorbance: -4 to +4.0 Abs), photometric accuracy (e.g., ±0.0015 Abs), wavelength accuracy (e.g., ±0.05 nm), spectral bandwidth (e.g., 1 nm or better), light source (tungsten and deuterium lamps), optics (e.g., double-beam, holographic grating), detector (e.g., silicon photodiode), and data connectivity (USB ports). Other key specs involve stray light, noise level, baseline stability, and on-board features like LCD displays, software, and hardware validation.
