It's also worth knowing whether the oxygen trace analyzer is equipped with data logging capabilities since it may be useful for reasons like identifying performance trends.
Prepare the Installation Location
Users should ensure the spot where oxygen trace analyzers will be installed and mounted are well-prepared. Conducting a safety check, such as ensuring there are no gas leaks and that the environment is temperature stable, will make a good installation platform. It's also necessary to make certain that there are power supply sources nearby and that the oxygen levels in the environment are safe for the analyzer to be installed in.
Mount the Analyzer
Follow the manufacturer's instructions regarding mounting the analyzer. Some are wall-mounted, while others must be placed on a desktop or pedestal mount. Ensure there is good accessibility for readings and routine maintenance. Just as important, the space around the analyzer must be well-ventilated so air can circulate freely.
Connect the Sampling Line
Use a sample line to connect the oxygen trace analyzer to the environment to measure. Ensure the sample line is made of a material compatible with the environment where oxygen levels are measured. After that, attach it to the analyzer's sample inlet port. Make sure there are no kinks or bends that may affect proper functioning.
Power Up
After mounting the analyzer, connect it to the power source as specified by the manufacturer's guidelines and instructions. Turn it on and let it boot fully. Some analyzers require an initial configuration, while others need calibration before beginning operation. Follow the manufacturer's guidance regarding configuration and calibration instructions.
Access the Display
Once the oxygen analyzer is switched on, its display panel will show the current oxygen level. This display is crucial for analyzing the amount of oxygen in a specific environment or space.
Calibration
