Characteristics
Thin-film-style keyboard,dust-proof,water-proof,and easy to clean.
To be avoid energy plummeting after reflector was burnt,it has adopt the lens of halogen tungsten lamp and deuterium lamp to gathering light.
Advanced optical system design,sealed grating monochromator,with a scientific mouldproof technology obviously improve the service life and the accuracy of stray light and stability.
with a professional lamp holder,you can replace the tungsten lamp and deuterium lamp freely without re-adjusting the optical circuit.
Automatic calibration 0%(T),**0%(T) and absorbency0(A).
boasts"concentration direct" and"concentration factor"functions.
With RS**2 interface can connect the PC software as the optional cost.
