Fison Double Beam UV Visible Spectrophotometer measures absorbance and transmittance across 190–1100 nm, providing ±0.5 nm wavelength accuracy. The Czerny-Turner monochromator isolates selected wavelengths, while the silicon photocell detector converts light signals into measurement data. Manufactured for quantitative testing in pharmaceutical, environmental, and food laboratories, this Double Beam UV Visible Spectrometer supports sample analysis and research workflows.
