Wireless colorimeter sensor

I. Working Principle

Monochromatic light emitted by a light-emitting diode passes through a transparent container holding the sample solution. A portion of the incident monochromatic light is absorbed by the solution, while the transmitted light is captured by a photodiode. The transmittance of the solution is then calculated based on this transmitted light.

VI. Usage Tips

1. Handle with care to avoid damage to optical and electronic components.
2. After use, rinse the sample cuvette with distilled water and store it properly, as this directly affects measurement accuracy.
3. Select the correct wavelength to obtain accurate results.
4. Typically, add 2.5–4 mL of test solution to the container, ensuring the liquid level is above the diode's emission angle to prevent measurement errors.
