Technical Data Sheet

 I.Host function

 Adopts microcomputer measuring system, T-A conversion, automatic adjustment 0% (T) and adjustment 100% (T),

 with GOTOλ, joint 8 sample holder automatically , the error of cuvette automatically deducted , multi-point calibration,

  the slope and intercept settings and other functions, with RS232 interface and parallel printer port (printer-specific, separately optional).

 

 II.Online features

 Through the RS232 serial interface, you can use the upper software for full wavelength scan, time scan,

  the regression equation (1, 2, 3 times), multi-wavelength testing, and greatly expanded testing capabilities (besides the host function).
