Product Details

Proportional spectrophotometer is a model launched for customers who pursue high cost-effectiveness requirements, with two configurations: host and software control. The instrument has a precision proportional monitoring dual beam optical system and a well-designed circuit control part. The host can independently complete the main functions of wavelength scanning, automatic zeroing, transmittance, absorbance, linear regression, etc. It has excellent accuracy, repeatability, linearity and stray light, noise indicators, a bandwidth of 2nm suitable for various application needs, a large screen LCD display, simple and fast measurement, stable and reliable quality.

　　System functions

System self-test: automatic wavelength detection, automatic filter detection and switching, energy detection, etc.

Light source switching: The light source switching point can be set arbitrarily within the specified range.

Light source switch: It can automatically turn on and off deuterium and tungsten lamps, extending the service life of the lamps.

　　Proportional spectrophotometerFeatures

The application of high-performance 1200L/mm ultraviolet grating, combined with the integration of monochromator optical path and imported photoelectric converter, ensures low stray light, high resolution, and high photometric linearity of the instrument.

The spacious sample chamber allows for the selection of 10cm sample racks according to different requirements, meeting the needs of special industries.

The use of imported long-life deuterium lamps and tungsten lamps ensures the high-quality requirements of the instrument for light source energy, enabling the instrument to remain in a high stability state for a long time, enhancing reliability, and extending the service life of the instrument.

Equipped with advanced automatic correction of wavelength error function, further ensuring the testing accuracy of the instrument.

The integration of computer and host, with Chinese/English touch screen interface and large-scale integrated circuit, makes it highly intelligent and automated, reflecting a sense of technology. It is smooth and convenient to use, and can read the relevant data and spectra of the tested sample clearly and intuitively in one go.

The instrument has testing functions such as photometry, quantification, regression equation, kinetic detection, and full wavelength scanning.

The USB interface can be equipped with peripheral devices such as computers, printers, software, keyboards or mice, and related operating tools.
