why test wavelength accuracy for spectrophotometer
NIST Traceable reference standards for verifying the wavelength accuracy of a UV/VIS spectrophotometer. All standards are stringently prepared according to NIST guidelines.NSG's solid-state standards never need to be replaced due to material aging and come with a unique lifetime warranty.IST Traceable reference standards for verifying the wavelength accuracy of a UV/VIS spectrophotometer.
