QVIS CS-2000 uses the changes of strength by absorption or scattering and so on when light passes the sample solution. Put sample solution and suitable reagent to water analysis Kit or 1 inch cell and measure the absorbance of solution after developed solution by simple manufacturing.

It is way that convert objective ingredient of sample solution to concentration by stored standard curve beforehand.

• QVIS uses holographic grating method without selecting filter method such as existent quality of water analysis instrument. Separating light by wavelength, it is available to choose 340nm~1100nm wavelength.
  
  
• QVIS is convenient to measure over 50 items such as Inorganics as well as COD, TN, TP, heavy metals because standard curve of items is stored beforehand. It is able to save 100 Standard curves directly to user mode by user.
  
  
• QVIS was manufactured via water analysis kit that reagent of a fixed rate is filled to cylindrical vial that diameter is 16mm. 1 inch cell and 1cm cell are available if change cell holder.
  
  
• QVIS's user interface can operate QVIS easily if user is accustomed to windows because is designed equally with Windows. because it is possible to connect to PC, user can confirm and control the result of sample solution by real-time in the circumstances of MS windows-98/NT/2000.
