Abstract: ABSTRACT Variable Path-Length Water-Proof In-Situ Colorimetric Probe The present invention relates to a variable path-length colorimetric probe system designed for flexible and accurate sample analysis. The system includes a customizable light source (101) that emits light at a wavelength matching the sample's absorbance, a detector (102) that captures transmitted light, and an adjustable gap (103) between the light source and detector, enabling the modification of path length to accommodate varying sample concentrations. An adjustable tip mechanism (104) allows manual or electronic adjustment of the gap, ensuring precise measurements without sample dilution. The system is housed in a waterproof casing (105) with sealed ports (106) for secure external connections. A microcontroller with Wi-Fi functionality (107) processes data and wirelessly transmits it for remote monitoring and analysis. Additionally, the positions of the light source and detector are interchangeable, providing adaptability for different experimental setups. This system enhances the efficiency, accuracy, and versatility of colorimetric analysis in various applications.
