Features: 

• Imported & Environmental Deuterium lamp, preventing from Ozone inhalation
• High-class grating with wholly hermetic light path design, ensures the super low stray light
• Real-time monitoring the lifetime of Deuterium lamp adn Tungsten lamp
• Socket-type Deuterium lamp and Tungsten lamp
• Wavelength calibration, wavelength setting, change light source and dark current calibration automatically.
• Si02 coating optical mirror, reduce the influence from outside
• Agriculture, Geogoly, Metallurgy and Environment etc. fields. 

Basic Functions: 

1. Photomery
 - Test Abs., Transmittance by fixed wavelength.

2. Quantiative:-
   - a) C Mode: Establish C= K*A curve, test sample concentration
   - b) F Mode: Establish A= K1*C+K0, test sample concentration
   - c) Display and save curve, test data (V-1200)

Photometry Mode                                              Con. Test C=K*A+B
