314BT便携式氧气分析仪，氧化锆传感器，台式（BT）附件
The Nova 314 Portable Oxygen Analyzer is designed to measure the oxygen concentration of 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.

320K便携式烟气氧分析仪，手提箱（K）外壳
The Nova 320 Series of Portable Flue Gas Oxygen Analyzers utilize a reliable, stable oxygen sensor which responds quickly to the oxygen present in a flue gas sample. Its life expectancy is between 3 and 4 years. The sensor is very easy for the customer to replace and at a reasonable cost.

A rechargeable ‘gel cell’ battery provides enough power for the pump and electronics for about 20 hours of continuous operation. The analyzer can still be operated while it is being charged. A red LED indicates when to recharge and a green LED indicates that it is receiving recharging power. The analyzer is supplied with a 12 ft. sample hose and a stainless steel probe.

The Model 320 can optionally indicate stack temperature (Model 320T; 0-1800°F or 0-1000°C) for doing fuel efficiency calculations. The temperature sensor is built into the sampling probe. Efficiency charts for each fuel are provided.

510RA-2缺氧报警监视器，4-20mA远传变送器输出，两个24VDC报警
The Nova 510 Series Oxygen deficiency or excess alarm monitors are designed as an O2 'watchdog' against accidental displacement of ambient air in a confined space by inert gases, or by a buildup of too much O2 from an O2 leak in the room.
The monitors all utilize a long life electrochemical O2 sensor. Actual O2 concentration is shown on a digital meter. Alarm set points are pre-set at Nova but are field adjustable if desired. A 'Sonalert' audible alarm with reset button is included.
