Overview
The YOKE T-U9 xenon arc dual beam of light UV-Visible Spectrophotometer uses pulsed xenon arc as the light source, and does not need to be replaced for at least 7 years of normal use. The instrument is based on excellent Optical inspection, circuit and structural design, combined with strict mass management system, microcomputer control and processing data, equipped with a large-screen color display interface, providing graphical operation and user-friendly menu prompts.
Features
1. Fast and convenient, ready to use, no need to preheat, using pulsed xenon light source, 1 billion flashes can be used for 7 years.
2. Equipped with a 10.1-inch color touch display, the large screen can directly display various scanning Linear dispersion and patterns, and the measurement can be completed without the help of a computer.
3. Support U disk storage, measurement data can be directly exported to U disk, support excel, txt, picture format, can output * .csv, * .qua, * .tet, * .bmp four formats.
4. Rich data output interface, equipped with RS-232C serial port (printing), USB drive (online), USB HOST (connected to U disk), and standard 32GB memory.
Using an excellent 32-bit Cortex_M3 processor, the main frequency can reach 120M, and the instrument can store 5000 test data or 500 working Linear dispersion.
6. Optical inspection system design with suspension is adopted to strengthen the thickened aluminum baseplate, effectively eliminating the impact of vibration or deformation on the Optical inspection system; double-decked design completely separates the optical path from the circuit part.
7. Using photoelectric signal detection device, the signal-to-noise ratio of the instrument is lower and the operation is more stable.
Principle
The instrument uses a dual beam of light Optical inspection system with a built-in reference monitor and a light source provided by a pulsed xenon arc. After the ray of light is split, the sample beam of light and the reference beam of light are formed. Through the sample and the reference channel, the silicon photodiode Detector receives the optical signal and converts it into an electrical signal. The instrument processes the signal through a photoelectric signal detection device, and the data is calculated and analyzed by a 32-bit Cortex_M3 processor. Finally, the results of transmittance, Absorbance, concentration or energy measurement are displayed on the touch screen.
Applications
Biochemistry, drug analysis, food testing, environment monitoring, materials science, quality control, teaching and research

Steps
1. Turn on the power supply of the instrument, and the instrument will be used immediately without preheating.
2. Enter the graphical operation interface through the 10.1-inch color touch screen, and set the measurement parameters (such as wavelength, luminosity mode, etc.) according to the menu prompts.
3. Put the sample to be tested into the automatic 8-cell sample chamber.
4. Start measurement, the instrument automatically performs dual beam of light scanning and data collection.
5. After the measurement is completed, the results and Linear dispersion are displayed directly on the touch screen.
6. You can choose to export the data through a USB flash drive (supports multiple formats), or output and store it through RS-232C and USB interfaces.
Notice
The instrument uses a pulsed xenon lamp light source, which has a long normal service life, but it is still necessary to avoid abnormal operations other than frequent switching.
• Be careful to keep the Optical inspection system clean to avoid dust or contaminants affecting the accuracy of the optical path.
• When using an automatic 8-cell, make sure the sample cell is clean and placed smoothly.
When exporting data, ensure that the USB flash drive format is compatible and remove the storage device safely.
• The instrument is double-decked design, the light path is separated from the circuit, and non-professionals should not disassemble the internal structure without authorization.
• Stability of the Optical inspection system should be maintained by avoiding strong vibration or sudden temperature changes in the operating environment.
