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 standard with single or dual  W L. It have wavelength scanning function using PC software. It is widely used in colleges and QC labs.



  1. Double beam optical system.
  2. Low noise and Low stray light.
  3. Large LCD display, can display curve.
  4. High quality grating, detector and lamps.
  5. Data and Curve can be stored in real-time.
  6. Auto setting WL, auto Blank.
  7. Lamps can be turned on/off individually.
  8. Easy to change Pri-aligned lamps.
  9. Reinforced baseboard and bracket assures durability.




  1. Photometric: T%, Abs.
  2. Quantitative: Standard Curve
