UV-Solution 2.0 Software Function Introduce:

1.Quantitative Test: Quantitative test curve calibration: Can make first-order, second-order and third-order standard curve fit measurement. Establish standard curve through 20 standard samples. Measurement is available under single wavelength, double wavelength and three wavelengths.
2.Parameters Calibration: Can make first-order, second-order and third-order standard curve fit measurement to calibrate curve parameters. Can choose single wavelength, double wavelength or three.
3.Data out-put: Data can be exported as a txt or bmp file for edit.
4.Dynamics measurement: Time scan, the test time could be 7 days. Sampling time could be optional (0.5,1, 2,5,10,30,60), could save 10000 test datas.
5.Wavelength scan: Use scanning increment (0.1, 0.2, 0.5, 1, 2,5nm) to scan sample in any wavelength range, data processing.
6.Multi-wavelength test: Up to 15 testing wavelength point.
