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).
