A reference standard for calibration, verification and adjustment of optical equipment for the measurement of colorimetric parameters, spectrophotometric and turbidity.

摘要

A reference standard for calibration, verification and adjustment of optical equipment, such as: colorimeters, fotocolorímetros, spectrophotometers and turbidimeters.The pattern consists of a plastic support (02) with a drawer (5) for housing an optical filter with a multilayer laminated absorption cover internal (04)A window (03) for passage of light generated by the optical instrument and a thread on the upper end for attachment of a cover and a plastic lid with screw.Depending on the application support changes of height and diameter and the optical filter change of multilayer.Each pattern will be accompanied by a certificate with the detailed values of analyte concentration and the absorbance corresponding to various wavelengths.
