TECHCOMP VIS-7200A Visible Spectrophotometer
TECHCOMP VIS-7200A Visible Spectrophotometer
Compact VIS-7200A Visible Spectrophotometer is ideal for routine applications in testing and
teaching area. Easy operation and reliable design are for fast yet accurate results.
Excellent Optical System
- The use of concave diffraction grating enhances the monochromator efficiency and reliability and allows the optical system to be simple and compact.
- Convex lens is used to focus the light beam for the micro volume sample analysis.
Highly Automatic Control Functions
- Self-test report of hardware.
- Built-in self-calibration function checks and calibrates the wavelength accuracy with holmium oxide glass filter every time when the instrument is switched on. The measuring wavelength is guarantee to be accurate.
- System memory stores the wavelength scan baseline as reference spectrum for blank subtraction.
Spectrum Scan Functions
- Abs & %T spectrum scan and display modes;
- Fast scan speed increase the throughput of the spectrum analysis.
Photometry/Quantification
- Calibration curve can be generated by using maximum 8 standard solution or by inputting the coefficient of correlation.
- Calculation and printout of the coefficient of correlation.
- Sample concentration can be calculated and printout after generating the calibration curve.
User-Friendly Display and Data Processing Functions
- Easy to use keypad and user-friendly display make the operation of instrument simple and intuitive.
- Large 3.5 inch LCD screen allows easy viewing of instrument status, spectrum scan and measurement data.
- Spectrum can be displayed and printed.
- Operation step-by-step wizard.
Compact and Versatile Design
- The instrument is compact in size while the sample compartment is large enough to accept variety of accessories for various methods and different sample handling.
- Comes with four cell holder for easy changing of cell.
