Photometric measurement: Double beam uv spectrophotometer can measure transmittance and absorbance at 1 to 6 wavelengths at the same time.
Spectral measurement: Perform spectrum scanning of transmittance, absorbance and energy within the wavelength range, and perform various data processing such as peak and valley detection, derivative calculation, spectrum calculation, etc.
Quantitative measurement: Single wavelength, dual wavelength, three wavelength and multi-wavelength measurement 1 to 9 point working curve (1 to 4 times) regression.
Kinetic measurement: Time scan of transmittance and absorbance at any set wavelength and various data calculations can be performed.
Data output: Data files and parameter files can be accessed, and measurement results are output in standard and universal data file formats.
Double beam spectrophotometers are suitable for a wide range of applications including general pharmaceutical, research, clinical laboratory and biochemical use.
Double beam photometry system, combined with advanced circuit measurement and control system, makes the instrument highly stable and extremely low noise.
The newly designed excellent optical system and high-performance holographic blazed grating ensure low stray light of the double beam spectrophotometer, allowing the instrument to operate stably at all wavelengths at four decimal places for absorbance values (2 decimal places for transmittance values).
Fully automatic control system and advanced design concepts ensure that the double beam spectrophotometer has high reliability and stability.
The detachable structure of the sample chamber design makes it easy to replace different accessories to meet different analysis needs.
The spacious open light source room design makes light source replacement more convenient.
Imported components are used in key parts to ensure high reliability of instrument performance.
The Chinese and English operating software developed under the Windows environment provides a wealth of unique color measurement analysis functions.
