P860 Oxygen Nitrogen Analyzer
This is a dedicated analyzer manufactured by Pionics. The instrument utilizes the paramagnetic method to measure the oxygen concentration in the gas mixture. Owing to the paramagnetic property of oxygen, the analyzer's sample stream is passed through the magnetic sensors, where the gas is attracted by magnets. The more oxygen it attracts, the higher the flow rate will be recorded. That means this analyzer can give accurate oxygen content readings.There is, however, a disadvantage to using this method. The device cannot be used to measure oxygen concentrations that are higher than 100 percent. This is because when passing through, oxygen will also be affected by the analyzer's flow stream, which may cause safety issues during its usage. The production and petrochemical industries are the primary users of this analyzer.
Apart from displaying the paramagnetic oxygen measurements, the analyzer can also measure the nitrogen content in the gas mixture. The nitrogen readings are derived using the thermal conductivity method. Nitrogen gas features low thermal conductivity compared to other gases, making it easier to detect by the analyzer sensor.While the analyzer can give accurate readings of nitrogen with up to 99 percent purity, be careful when using gas mixtures with high carbon dioxide concentrations. This is due to the fact that carbon dioxide will affect the sensor and give inaccurate values.The oxygen and nitrogen meter features a 3.5-inch LCD that displays both the oxygen and nitrogen measurements simultaneously. The screen also features a backlight that allows the user to operate it in dark areas or at night.
Portable analyzer
This is an oxygen and nitrogen analyzer by Pionics known for its portability. The analyzer weighs only 1 kg, making it lightweight for easy and convenient carrying. The portable design allows it to be operated in various locations without the need for an electric outlet, as it is powered by a rechargeable battery. The battery has a life of 10 hours, ensuring the analyzer's usage does not interfere with monitoring or other activities.
The analyzer has a resolution of 0.1% oxygen and nitrogen purity, while the accuracy is ±1% for nitrogen and ±0.5% for oxygen. The range for oxygen is 0%–100%, while nitrogen is 0%–99%. A quick check can be made with the readings every 30 seconds. This is facilitated by the fast response time.The portion of the LCD that displays the analyzer readings is also customizable, enabling the user to select the measurement units that are easy for them to work with. These features make the analyzer efficient for field measurement.
Fixed analyzer
The fixed analyzer, unlike the portable one, is installed permanently in a chosen location for continuous monitoring and doesn't require easy movement. The device offers constant readings, which are beneficial for industries that need steady gas composition data.The analyzer can be conveniently connected to a data collection system, allowing users to gather and analyze their data on a computer for better efficiency in operations. This model is ideal for facilities that require a constant check on gas mixtures.Essential features like stability and accuracy make this device suitable for long-term operation without requiring frequent recalibrations or adjustments. This device will enable industries to monitor essential gas levels reliably.
As mentioned earlier, an analyzer's main function is to measure the gas composition and, at the same time, can also determine the nitrogen content using thermal conductivity. The simultaneous measurement of oxygen and nitrogen makes it a time saver for professionals.The nitrogen precision is based on the oxygen reading, meaning that when there are nitrogen impurities in the oxygen gas, the analyzer will give neglible nitrogen readings. Conversely, if nitrogen has higher purity, it can also detect oxygen traces. That being said, the analyzer's nitrogen readings depend on the purity of the gas being measured.
Consider the accuracy and resolution metrics of the P860 analyzer. Higher values will give higher measurement accuracy. So, select an analyzer whose fuel gas is compatible with the accuracy and resolution metrics.P860 analyzers come with features for data logging and transmission for analysis. Choose a model that best matches your requirements regarding these features. Laser analyzers are available with different service intervals, which can have an impact on maintenance costs. Select a model that offers long service intervals, so the analyzer does not need to be often serviced. Some P860 oxygen nitrogen analyzers are manufactured with materials that can withstand corrosive gases. Select these models if the gases to be measured are known to be hostile.
There are fixed and portable P860 oxygen nitrogen analyzers. The choice will depend on where the measurements will be taken. A portable analyzer is for spot checks, while a fixed one is for continuous monitoring. Consider what ambient conditions the analyzer will work in. There are models that feature enclosures to protect the internal components from dust and moisture. Consider the working temperature range. Ensure the analyzer you select can work at the temperatures that are required in your facilities.
A1: They are primarily used in the petroleum industry to measure the composition of gases in pipelines and tanks. This helps them know the percentage of oxygen and nitrogen in the gas, which is important for refining and extraction processes. Chemical manufacturers also use them to monitor gases used in making chemicals to ensure they have the right mixture. These are also used in semiconductors, where pure gases are needed for manufacturing. The space and rocket industry relies on these analyzers to measure fuel mixtures for accuracy in performance and safety. Owing to its versatility, it's ideal for numerous monitoring and calibration applications across industries.
A2: Yes, there are P860 oxygen nitrogen analyzers manufactured with enclosures sealed to prevent dust ingress. Such analyzers also have provisions to protect the internal components from moisture. Hardware protection is necessary for measuring instruments that operate in hostile environments.
A3: These analyzers are manufactured with different service intervals. There are models that should be serviced frequently, which can have an impact on the maintenance costs. There are also P860 analyzers that require service only after a long time, so they are more economical.
A4: These devices are manufactured to measure oxygen and nitrogen concentrations in gas mixtures. No, they use the paramagnetic principle and thermal conductivity methods to measure oxygen and nitrogen, respectively. Some analyzers can also measure hydrogen or carbon dioxide if they contain lesser concentrations in the gas mixture.
