Fundamental:
● The spectrophotometer analysis method is based on the selective absorption of electromagnetic radiation by substances with different molecular structures.
● Applied electromagnetic radiation spectrum area is usually visible spectrophotometer from 330nm to 800nm.
Application:
Using microprocessor control technology to qualitatively and quantitatively analyze substances in the visible spectrum region, it is a necessary multi-purpose analytical instrument for routine laboratories. It is used in clinical testing, biochemistry, petrochemical industry, environmental protection, quality control and tertiary education. College teaching laboratories and other departments.
Features:
- With backlit LCD display, the reading is clear and clear.
- The advanced holographic blazed grating C-T monochromator has the advantages of high wavelength accuracy, good monochromaticity and low stray light.
- Using microcomputer measurement system, T-A conversion accuracy is high, and there are automatic adjustment of 0% (T) and 100% (T), direct density reading, concentration factor setting, and serial data printer can be selected for data printing.
- The measurement reading has high accuracy, good repeatability and stability.
- Optional printer (Purchasing separately).
- UVWin7 software package (Pruchasing separately).
- Can be used with 250px cuvette (100mm), specially for sugar industry, power plant, water plant, chemical industry and other low content measurement.
