This paper presents the development of a portable device that can be used for liquid identification using the concept of Beer-Lambert law. The final device can recognize up to 30 different materials in their liquid state and provides some other useful features that can enhance its operation. The user can set a group of 30 liquids according to specific needs and applications. The device can provide the user with some specific settings to start the measurements. The volume of a fluid is identified by a 4 mL sample inserted in the cuvette, then the user can start measuring the concentration of some common solvents like methanol, ethanol, etc. by passing a light of different wavelengths through the sample. The amount of the transferred light is measured using photodetectors and the readings depend on the amount of absorption. The amount of absorption depends on the sample types, colors, contents, and concentrations, so it is used as the main indicator to identify a specific sample.
本文介绍了一种便携式设备的研发情况，该设备可利用比尔-朗伯定律的概念用于液体识别。最终的设备能够识别多达30种不同的液态物质，并具备一些其他有用的功能来提升其操作性能。用户可以根据特定需求和应用设置一组30种液体。该设备可以为用户提供一些特定设置以启动测量。通过插入比色皿中的4 mL样品来识别流体的体积，然后用户可以通过让不同波长的光穿过样品来开始测量一些常见溶剂（如甲醇、乙醇等）的浓度。使用光电探测器测量透射光的量，读数取决于吸收量。吸收量取决于样品类型、颜色、成分和浓度，因此它被用作识别特定样品的主要指标。
