314K氧化锆式便携氧气分析仪
314K氧化锆式便携氧气分析仪是用来衡量一个干净，干样气中的氧浓度。在操作中，一个内置的投篮样品注入分析仪，并通过采样调节过滤器，流量计和氧传感器的样气。外部气体洗涤器可用于消除任何腐蚀性气体进入分析仪之前，如果需要的话。氧化锆传感器是通过安装在一个块，通过它流的样气流量。该传感器产生的非线性μA的输出正比于氧的浓度。这种非线性信号，然后线性和氧的处理器板放大

larger image	The Nova 314 Portable Oxygen Analyzer is designed to measure the oxygen concentration of a clean, dry sample gas. In operation, a built-in sample pump draws the sample gas into the analyzer and through the sample conditioning filters, flow meter and O₂ sensor. An external gas scrubber is available to remove any corrosive gases prior to entering the analyzer, if required. The zirconia sensor is mounted in a flow-through block through which the sample gas flows. The sensor produces a non-linear µA output proportional to the oxygen concentration. This non linear signal is then linearized and amplified by an O₂ processor board. The output is then directed to a main amplifier board which then connects to the digital readout meter and optional recorder output terminals.

Applications

For continuous high accuracy analysis from PPM to 96% Oxygen (O₂) in process gas streams. Other applications include combustion air O₂ enrichment, flue gas analysis, O₂ deficiency analysis, and many more. Note: Sample gas must not contain combustible gases or vapors.

Calibration

Analyzed calibration gas of O₂-free nitrogen (N₂) for zero
Air @ 20.9% O₂ or analyzed calibration gas of O₂ in N₂ for span

Unique Applications

The 314 series analyzers should not be used on sample gases containing flammable gases. These gases will be burned by the zirconia sensor along with any available O₂ and cause the analyzer to display readings that are lower than the actual values.

All Nova analyzers are built using proven technologies and techniques. If this product does not suit your application, please contact Nova. In many cases, we are able to build an analyzer specific to your needs.
