I. Working principle

The monochromatic light emitted by a light-emitting diode passes through a transparent container containing a solution sample, and then part of the monochromatic incident light is absorbed by the solution, while the other transmitted light is absorbed by a photodiode. According to the transmitted light, the The transmittance of the solution.

VI.Usage Tips

1. Use with caution and beware of damage to optical and electronic devices.
2. When you are finished using it, rinse the sample colorimetric bottle with distilled water. It is very important to keep the colorimetric tube well, which is directly related to the accuracy of measurement.
3. Choose the right wavelength to get the right results.
4. Generally add 2.5 to 4 ml of test solution to the container to ensure that the liquid level is above the emission angle of the diode. Otherwise, errors will be caused in the measurement results.
