摘要
本文介绍了一种基于光耦合器的水中氧气饱和度调节装置（OptoReg）。该系统使用 FireSting-O2 测量仪、光耦合器盒和电子开关盒控制氧气和氮气电磁阀。硬件组件通过通用串行总线（USB）电缆与电脑连接。控制软件是免费的，具有图形用户界面，易于使用。有了 OptoReg 系统，任何实验室只要有一台运行 Microsoft Windows 操作系统的计算机和一个 4 通道 FireSting-O2 计，就能轻松、廉价地建立四个独立控制的系统，用于调节水中的含氧量。在此，我们将介绍如何组装和运行 OptoReg 系统，并提供一组数据，证明 OptoReg 系统在静态适应实验和动态升温试验中的高精度和稳定性。
The OptoReg system: a simple and inexpensive solution for regulating water oxygen.
This paper describes an optocoupler-based regulation apparatus for saturation manipulation of oxygen in water (OptoReg). This system enables control of solenoid valves for oxygen and nitrogen gases using a FireSting-O2 meter, an optocoupler box and an electronic switch box. The hardware components connect to a computer through Universal Serial Bus (USB) cables. The control software is free and has a graphical user interface, making it easy to use. With the OptoReg system, any lab with a computer running Microsoft Windows operating system and a 4-channel FireSting-O2 meter can easily and cheaply set up four independently controlled systems for regulating water oxygen levels. Here, we describe how to assemble and run the OptoReg system and present a data set demonstrating the high precision and stability of the OptoReg system during static acclimation experiments and dynamic warming trials.
期刊介绍：
Conservation Physiology is an online only, fully open access journal published on behalf of the Society for Experimental Biology.
Biodiversity across the globe faces a growing number of threats associated with human activities. Conservation Physiology will publish research on all taxa (microbes, plants and animals) focused on understanding and predicting how organisms, populations, ecosystems and natural resources respond to environmental change and stressors. Physiology is considered in the broadest possible terms to include functional and mechanistic responses at all scales. We also welcome research towards developing and refining strategies to rebuild populations, restore ecosystems, inform conservation policy, and manage living resources. We define conservation physiology broadly and encourage potential authors to contact the editorial team if they have any questions regarding the remit of the journal.
