Host function:
The measurement system based on microcomputer, T-A Conversion accuracy, automatic adjustment 0% (T) and 100% (T), with GOTO lambda, automatic 8 Combined sample holder, automatic deduction error cuvette, concentration of multi point calibration, slope and intercept settings and other functions, has RS232 Interface and parallel printer port (printer, separately optional).
Online function:
adopt RS232 The serial interface, can be used for full wavelength scanning, using the software time to scan, concentration (regression equation 1 times, 2 times, 3 times ), multi wavelength test, and greatly expand the test function (except the main function).
