Overview
The 721G-100 visible spectrophotometer is an analytical instrument of the SHANGFEN brand. It uses microprocessor control technology to perform qualitative and quantitative analysis of substances in the visible Light spectrum. This model is a multi-purpose analytical instrument in a conventional laboratory. The main difference between this model and the 721G model is that the test sample chamber is widened and the standard 10cm Colorimetric dish is equipped. It is especially suitable for the analysis of solutions with low concentration in the sugar industry, power plants, water plants, chemical industries and other fields.
Features
1. The holographic blazing grating monochromator has the advantages of high wavelength accuracy, good monochromaticity and low stray light.
2. Adopt backlit LCD display to avoid the reading error of pointer display.
3. Using microcomputer measurement system, T-A conversion accuracy is high, with automatic adjustment of 0% (T) and 100% (T), concentration factor setting and concentration direct reading function.
4. High measurement accuracy, good reproducibility and Stability.
5. Using automatic light gate technology, no blackbody is required, which can protect the photoelectric Sensor.
6. Standard 10cm Colorimetric dish holder, optimized for low concentration solutions.
Principle
The instrument works based on the principle of selective absorption of light by matter (Lambert-Beer's law). After the composite light emitted by the light source is split by a monochromator (holographic blazing grating), it becomes monochromatic light of a specific wavelength. When the monochromatic light passes through the sample solution under test, part of the light is absorbed. The transmitted light is received and converted into an electrical signal by the Detector (imported Photocell, photovoltaic cell), which is processed by a microprocessor system, and finally the light transmitance (T) or Absorbance (A) value is directly displayed on the LCD display, so as to realize qualitative or quantitative analysis.
