历史上与研究相关的复杂传感器和工具的高成本限制了它们的采用，只有相对较少的资金充足的研究人员。本文提供了一种方法，应用开源的方法来设计和开发的色度计。讨论了一种仅利用开源硬件和软件解决方案以及现成的分立元件的3-D可打印开源色度计，并将其性能与商用便携式色度计进行了比较。使用为密闭回流化学需氧量（COD）方法制备的商业小瓶评价性能。这种方法将可靠的封闭回流COD的成本降低了两个数量级，使其成为绝大多数潜在用户的经济替代方案。该开源色度计表现出良好的重现性，并可作为进一步开发和推导其他类似用途（如浊度法）的设计的平台。这一方法使最需要的国家、欠发达国家和发展中国家的实验室能够前所未有地获得基于低成本传感器的精密仪器。
The high cost of what have historically been sophisticated research-related sensors and tools has limited their adoption to a relatively small group of well-funded researchers. This paper provides a methodology for applying an open-source approach to design and development of a colorimeter. A 3-D printable, open-source colorimeter utilizing only open-source hardware and software solutions and readily available discrete components is discussed and its performance compared to a commercial portable colorimeter. Performance is evaluated with commercial vials prepared for the closed reflux chemical oxygen demand (COD) method. This approach reduced the cost of reliable closed reflux COD by two orders of magnitude making it an economic alternative for the vast majority of potential users. The open-source colorimeter demonstrated good reproducibility and serves as a platform for further development and derivation of the design for other, similar purposes such as nephelometry. This approach promises unprecedented access to sophisticated instrumentation based on low-cost sensors by those most in need of it, under-developed and developing world laboratories.
