GD-723N Single Beam Scaning Visible Light Spectrophotometer
- Model GD-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
- The instrument 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.
