Â
Operating a Nitrogen Dioxide Analyzer:
Power On
- Ensure the analyzer is properly connected to a stable power source.
- Follow the manufacturer’s guidelines for turning on the device.
Warm-up Period
- Allow the analyzer to warm up for the recommended duration to ensure accurate readings.
Zero Calibration
- Perform a zero calibration in clean air or a zero-grade nitrogen source.
- Follow the device instructions for zero calibration, as it varies among models.
Span Calibration
- Use a certified NO2 calibration gas to perform a span calibration.
- Follow the manufacturer’s guidelines for the span calibration procedure.
Sample Intake
- Ensure the sample inlet is free from obstructions and connected to the area where NO2 measurements are needed.
Data Logging and Recording
- If your analyzer has data logging capabilities, set up the logging parameters.
- Regularly record measurements, noting the date, time, and location of each reading.
Â
Maintaining a Nitrogen Dioxide Analyzer
Regular Inspections
- Conduct routine visual inspections for any physical damage, loose connections, or signs of wear.
Sensor Maintenance
- If your analyzer has a replaceable sensor, follow the manufacturer’s guidelines for sensor maintenance and replacement.
Filtration System
- Check and replace filters as recommended by the manufacturer to prevent contamination.
Calibration Checks
- Regularly perform calibration checks to ensure the accuracy of the measurements.
- If discrepancies are found, follow the calibration procedures outlined by the manufacturer.
Power Supply
- Ensure a stable power supply and address any power-related issues promptly.
