Ecotech水环境自动控制系统（水温、溶解氧、pH/CO2、盐度）系统 

Ecotech水环境自动控制系统（水温、溶解氧、pH/CO2、盐度）系统能够对水温、溶解氧、pH/CO2、盐度等环境参数进行监测、记录和调节。仅需一台电脑，即可同时对多个鱼缸、水族箱的一个或者多个参数进行同步、自动调控，使之达到预设值或者运行自定义程序。

      工作时，多台测量设备连接到一部电脑，软件通过蓝牙（无线）或者以太网（有线）控制水泵或者电磁阀，响应测量数据进行实时调控。

       软件支持Win10/11系统，简单易用，对于四个环境参数的任意一个，它使数据记录、传感器校准、测量单位的更改、自动程序的设定等步骤变得轻松友好。使用者可根据具体的研究应用自定义运行程序，包括分级调节或者正弦模式，以模拟日变化等自然波动。而且程序能够被保存和加载，以便进行快速、一致性的设置。

Ecotech水环境自动控制系统（水温、溶解氧、pH/CO2、盐度）系统具体配置

1.OmniCTRL软件

软件既能够和监测水环境参数的设备无缝通信，也能够通过控制水泵/电磁阀对水环境参数进行调节。配合相应的硬件，可同步调控不同的参数，如水温和溶解氧；既能单向调控（参数调高或调低），又能双向调控（参数调高和调低）。软件实时显示实验过程中的每个水环境参数。所有图表都能够按照喜好进行编辑，导出至Excel或保存成图像。所有记录数据也能够被保存和导出成.csv文件，以便于在Excel中进一步分析。

2.PowerX4工业级四位插座及远距离蓝牙适配器

PowerX4四位插座能够实现基于软件驱动的控制，通过以太网或蓝牙的方式对水泵或电磁阀的开闭进行控制。每个延时控制的电参数（例如输入电压和功耗等）能够被软件监测和记录，以便于对所连接的设备进行诊断。远距离蓝牙适配器包括1类蓝牙适配器和外接天线，能够将常规PC（2类蓝牙）的无线距离翻倍。

3.水环境监测和控制单元

可分为温度、溶解氧、盐度、pH/CO2、溶解氧&温度、盐度&温度、pH/CO2&温度共计7种配置。每种配置包括相应的监测单元（溶解氧测量仪、pH测量仪、盐度测量仪等）和控制单元（水泵、电磁阀、管路等）。如下图为pH/CO2自动控制系统组成如下图（分别为单向调控和双向调控）：
