Ⅱ、Product Features

1. Photometric Measurement: Select your desired single-point test wavelength and measurement method to determine the absorbance or transmittance of the sample.
2. Quantitative Measurement: Measure unknown sample concentrations using curves with known parameter factors or by automatically generating standard solution curves; supports first-order, second-order, and third-order curve fitting methods; supports multiple measurement methods, including single-wavelength method, dual-wavelength method, dual-wavelength coefficient method, and triple-wavelength method; standard curves can be stored and recalled.
3. Spectral Scanning: Set a wavelength range and scanning interval, then measure the absorbance, transmittance, and energy of solid or liquid samples at intervals. The measured spectra can also be overlaid, scaled, peak/valley detected, saved, and printed.
4. Time Measurement: Time measurement, also known as kinetic measurement, scans the sample over a time range at a set wavelength point to measure absorbance or transmittance. Multiple spectrum processing methods are available for the measured spectra, including overlaying, scaling, and peak/valley detection.
5. Multi-wavelength Measurement: Allows for measurement of sample solutions at multiple wavelength points. Based on the set wavelength points, the absorbance or transmittance of the sample solution at multiple wavelengths is measured.
6. Auxiliary Functions: Deuterium lamp and tungsten lamp cumulative operating time, independent switching on and off of deuterium and tungsten lamps, selection of UV and visible light switching wavelength points, operating language selection, dark current correction, automatic wavelength calibration, etc.
