氧中氢分析仪和氢中氧分析仪工作原理
氧中氢分析仪和氢中氧分析仪工作原理，FTC320和FTC130设备都可以通过RS232接口来获取数据。其中FTC320采用了坚固的IP65防护等级设计，可以在-20°C到+50°C的温度范围内工作，并且能够承受高达20 bar的压力。对于氧中氢和氢中氧的测量，其氧气的最小检测范围为0至0.5 vol.%（相当于5000ppm），而氢气的最大检测范围则为98% Vol.至100% Vol.。该设备具有每周100ppm的零点漂移，测量噪声为50ppm，每摄氏度有5 ppm的温度依赖性。
FTC320 with O2 module with additional oxygen measurement
An optional add-on module for oxygen measurement extends the application range of the FTC320 to non-binary gas mixtures with oxygen content. The electrochemical cell has a long service life of 1 to 6 years. The cell can be replaced by the customer.Oxygen concentrations from 0-100 vol.% can be measured selectively. The measured concentration can be used for cross sensitivity compensation. The additional module is pneumatically connected to the gas output of the FTC320. The voltage supply, operation and all interfaces run via the FTC320. The measured oxygen concentration is shown on the display.If required, adjustment can be made via the operating menu or via the RS232 interface of the FTC320. Due to an internal compensation of the pressure dependency, the oxygen content can be measured reliably even in case of pressure fluctuations.
FTC320和FTC130氧中氢分析仪以及氢中氧分析仪采用先进的热导式原理，能够准确测量二元组份气体的量程高达0-100%Vol。其显示分辨率更是达到了惊人的1ppm，并且线性可达1%FS，响应时间极快，只需短短1秒（T90）即可完成测试。
The FTC320 is the new generation of our thermal conductivity analyzers. With the new electronics, the measurement accuracy has been improved compared to the FTC300. The already low noise of our analyzers has been further reduced. This is particularly crucial for measurements in the trace range.New measurement tasks can be realized with the FTC320. In particular, the possibility of cross-sensitivity compensation using external signals has been expanded. This is made possible by the larger program memory and significantly more computing power. A good example from the practical application is the use of the additional module for oxygen measurement. The increased computing power of the FTC320 allows cross-sensitivity compensation in real time.
For a more intuitive use, the operating menu has been slightly revised. As usual, data access is possible via an RS232 interface. The mounting dimensions as well as the analog interfaces (4-20mA, 0-10V and relays) stay the same compared to the FTC300. Those who are familiar with the FTC300 will also quickly get to work with the FTC320.
