Double Beam UV/VIS Spectrophotometer
spectrophotometer is double beam optical system can restrain drift, compensates for blank changes, Suitable for long time test. It is simple to fit a curve by using your standar d with single or dual W L. It have wavelength scanning function using PC software. It is widely used in colleges and QC labs.
