1. Photometry: The transmittance and absorbance at 1~6 wavelengths can be measured simultaneously.
2. Spectral measurement: scan the spectrum of transmittance, absorbance and energy within the wavelength
range, and can conduct various data processing such as peak and valley detection, derivative operation,
spectrum operation, etc.
3. Quantitative measurement: single-wavelength, two-wavelength, three-wavelength, and multi-wavelength
determination of the 1-to 9-point working curve (1-4 times) regression.
4. Kinetic determination: the time scanning of transmittance and absorbance is performed at any set wavelength,
and various data operations can be performed.
5. Data output: The data files and parameter files can be accessed, and the measurement results are output in a
standard general data file format.
