สเปคโตรโฟโตมิเตอร์ที่มองเห็นได้ด้วย UV (CAT หมายเลข ET-2) 7200

Compact VIS-7200 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.

This instrument can be used to measure the hue of all colors, and measure accurately CIE_Lab color, CIE_XYZ color, CIE_xyY color and RGB color. Also, it can display directly the color difference between two samples. It gets power supply from a 9V battery (or 12VDC power supply) with low power consumption, small in volume, light and easy to operate. It can measure variously smooth surfaces. It is stable performance, precise and reliable measuring results. It is excellent in performance mainly used in color matching of color system in costumes, furniture, architecture and upholstery etc, also applicable in design, printing, costumes and dyeing etc. The ET-45 facilitates easily to use, enhances the working efficiency greatly and reduces the communication cost.
