It integrates cloud storage, wireless connectivity and powerful data processing functions. It has High Accuracy and High Stability Optical Properties for a variety of Light spectrum measurement and quantitative analysis scenarios.
Features
1. Using 7-inch high-resolution (1024 * 768) color touch LCD display, the operation interface is friendly and simple.
2. Support cloud storage function, you can scan to add YOKE@Cloud data program through WeChat to expand the application scene.
3. Adopt "Shining Holographic grating" C-T monochromator and 24-bit High Accuracy AD chip of American AD company, with low stray light (less than 0.1T%), High Accuracy and High Stability (0.002A).
4. With strong storage capacity, it can store 2000 pieces of data and 96 pieces of Linear dispersion.
5. Standard USB interface, WIFI module and Bluetooth module, support wireless Bluetooth printing, connect special computer software to manage data, and export Excel editable data through U disk.
6. Light spectrum measurement, quantitative measurement, data storage and other rich functions.
Principle
The instrument works based on the UV-Vis Spectrophotometric method, spectra-trophotometry principle. The composite light emitted by the light source is separated by the blazing Holographic grating in the C-T monochromator to form monochromatic light. After the monochromatic light passes through the sample solution, it is received and converted into an electrical signal by the silicon photodiode Detector. The electrical signal is converted into a digital signal via the High Accuracy AD chip, and the final parameters such as the light transmitance (T%) or Absorbance (A) of the sample are calculated and displayed by the processor.
Applications
Chemical analysis, biological testing, environment monitoring, food inspection, pharmaceutical research and development, teaching experiments
Standards
The data did not mention specific compliance criteria.
Steps
1. Turn it on and warm up.
2. Measurement mode (such as Light spectrum measurement or quantitative measurement) is selected through the touch screen.
3. Put in the reference solution and the sample to be tested.
4. Instrument calibrating (e.g. zero setting, wavelength setting).
5. Start measurement and read data.
6. Data can be stored, exported or printed via USB, WiFi, Bluetooth or USB flash drive.
Notice
• Instruments should be placed in a stable, non-strong electromagnetic interference environment.
• It needs to be fully preheated before use to ensure the stability of the light source.
• Colorimetric dishes should be cleaned before and after use to avoid contamination affecting the measurement results.
• Colorimetric surface clean and in the right direction during measurement.
• Pay attention to the wavelength range of the instrument (195~ 1020nm) and avoid using it at non-applicable wavelengths.
• Periodic instrument performance calibration to ensure measurement accuracy.
When connecting external devices (e.g. printers, USB flash drives), follow safe operating practices.
