Model 723N Visible Spectrophotometer is an intelligent product with single-chip microprocessor control technology so that it has many sophisticated functions possessed by large high-end instruments and can meet the requirements of qualitative and quantitative tests for most samples conducted in conventional laboratories. The instrument is widely used in medical and health, clinical examination, biochemical, petroleum chemical, environmental protection and quality control departments, etc. The instrument with a low price and high performance is your best choice.
Main Characteristics
GD723N Visible Spectrophotometer adopts a 5.8” LCD graphic display and an externally linked thermal sensitive printer as its display and output devices to give a clear display of test results and prompts during the operation procedures. The thermal sensitive printer can easily print out test results for making data report and retention.
Test method offers photometric mode, wavelength scanning, quantitative analysis and dynamical analysis and multi-wavelength test mode. In the quantitative test mode, three normal analytical methods of factor input, single-point and undetermined multiple-point are offered.
Unique cell-matching function eliminates measurement errors caused by cell-matching (effective only in the photometric mode and quantitative analysis)
It has the function of automatic zero and full scale adjustment
It is highly accurate in measurement reading and excellent in repeatability and stability
The instrument has many advanced functions such as concentration direct reading, linear regression, timing print, GOTOl and spectrum scanning and the like
Sampling at different wavelength intervals of 0.1nm, 0.2nm, 0.5nm, 1nm, 2nm and 4nm can be made according to users’ requirements.
