Microprocessor UV-VIS Double Beam Visible Spectrophotometer

Mode: BL-2704 

Double Beam UV/VIS Spectrophotometer

Spectrophotometer is double beam optical system can restrain drift, compensates for blank changes. Suitable forlong time test. It is simple to fit a curve by using your standard with single or dual WL. It have wavelength scanning functionusing PC software. It is widely used in colleges and QC labs.

Main Features

Double beam optical system Low noise and Low stray light

Large LCD display, can display curve High quality grating.

Detector and lamps Data and Curve can be stored in real-time.

  Auto setting WL. auto Blank Lamps can be turned on/o individually

Easy to change Pri-aligned lampsReinforced baseboard and bracket assures durability
