Product functions

1. Photometric measurement: You can select the single-point test wavelength and test method you need within the range of 320-1100nm to measure the absorbance or transmittance of the sample. You can also directly read the concentration of the sample by entering the standard concentration or concentration factor.

2. Quantitative measurement: Measure sample solutions of unknown concentrations through curves of known parameter factors or automatically establish standard solution curves; with first-order\first-order zero-crossing, second-order, third-order curve fitting, and single wavelength correction, dual wavelength correction, three-point method optional; standard curves can be stored and called.

3. Qualitative measurement: Set a wavelength range, scan intervals, and then measure the absorbance, transmittance, reflectivity and energy of solid or liquid samples at intervals. You can also overlay, zoom, smooth, filter, peak and valley detection, save, print, etc. of the measured spectra.
4. Time measurement: Time measurement is also called kinetic measurement. The sample is scanned at intervals of the time range of absorbance or transmittance at the set wavelength point. The absorbance can also be converted into concentration or reaction rate calculation by inputting the concentration factor.
Enzyme kinetic reaction rate calculation. You can also choose from a variety of spectrum processing methods such as superposition, scaling, smoothing, filtering, peak and valley detection, and derivation of the measured spectrum.
5. Multi-wavelength measurement: It can set multiple wavelength points to measure the absorbance or transmittance of the sample solution. N wavelength test wavelengths can be set to test the absorbance and transmittance values at a single wavelength.
6. Instrument calibration measurement: Built-in special wavelength maximum allowable error calibration, transmittance maximum allowable error measurement, and stray light measurement.
7. Additional functions: deuterium lamp, tungsten lamp lighting cumulative time, deuterium lamp, tungsten lamp independent shutdown and opening, ultraviolet and visible light switching wavelength point selection, operating language selection (Chinese, English), wavelength automatic calibration, Bluetooth function, etc.
8. Optional PC reverse control software package functions: quantitative measurement, qualitative measurement, time measurement, multi-wavelength measurement, 3D graphics analysis, spectrum overlay analysis, etc.
