The Model 3000TA makes the task of trace oxygen analysis easier, faster and more precise than ever before. Simple menu choices, membrane command switches and a large LED display make setup and operation clear and quick.（3000TA型使痕量氧分析任务比以往任何时候都更容易、更快和更精确。简单的菜单选择，膜命令开关和大型LED显示屏使设置和操作清晰快捷。）
Air Calibration（空气校准）：
The high-accuracy and fast response of this model is only surpassed by its ability to calibrate without the assistance of support gases. The Micro-fuel Cell produces and output that is linear and enables the use of ambient air for calibration. The model also accommodates the use of a certified ppm O2 span or zero gas which speeds calibration when necessary and confirms the system is leak free.（该型号的高精度和快速响应是超越它的校准能力，没有辅助气体的协助。微型燃料电池的生产和输出是线性的，并能够使用环境空气进行校准。该型号还适用于使用经过认证的ppm O2跨度或零气体，在必要时加速校准，并确认系统无泄漏。）
User-Configurable Ranges（用户可配置的范围）：
Three user-configurable ranges are come standard with this model. When changing ranges, you are provided with excellent linearity of analysis precluding recalibration. Two programmable concentration alarms will provide the versatility to satisfy nearly any requirement.（三个用户可配置的范围是标准与此模型。当改变量程时，您可以获得线性分析，避免重新校准。两个可编程浓度报警器将提供通用性，以满足几乎任何要求。）
Custom Engineering（客户定制）：
The 3000TA can be ordered as a standard unit or as part of a larger analytical system. The options for this model are as follows.（3000TA可以作为一个标准单元或作为一个更大的分析系统的一部分订购。此模型的选项如下。）
C：Auto cal/zero with integrally mounted control valves（自动调零与整体安装的控制阀）V：Vacuum service（真空服务）K：19"rack mount with either one or two control units（19“机架安装与一个或两个控制单元）S：Stainless steel cell block（不锈钢电池块）
In addition, special sensors, custom engineered analyzers and complete monitoring systems can be suppled to satisfy unique applications.（此外，特殊的传感器，定制设计的分析仪和完整的监测系统可以满足应用。）
Maintenance-Free免维护：
The model uses a specifically qualified fast recovery InstaTrace Micro-fuel Cell to measure trace levels of O2 in the sample gas. This sensor sets industry standards for accuracy, sensitivity and ease of use. The InstaTrace is a sealed electrochemical device with no electrolyte to charge or electrodes to clean, making it maintenance-free.（该模型使用了InstaTrace微型燃料电池(InstaTrace Micro-fuel Cell)来测量样品气体中痕量的O2。该传感器为精度、灵敏度和易用性设定了行业标准。InstaTrace是一种密封的电化学设备，不需要充电电解液，也不需要清洁电极，因此无需维护。）
Convenient Outputs输出便利：
The standard 0-1 VDC and isolated 4-20 mADC outputs are provided for oxygen measurements and range identification. For 2 way communication, an RS-232C serial interface is incorporated to converse with a host computer for remote monitoring and control of zero and span calibration.（标准0-1 VDC和隔离4-20 mADC输出提供氧气测量和范围识别。采用RS-232C串行接口与上位机进行双向通信，实现对零点和量程校准的远程监控。）
