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.

 

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.

 

Calibrating a Nitrogen Dioxide Analyzer

Zero Calibration

  • Follow the manufacturer’s instructions to perform zero calibration in clean air.

Span Calibration

  • Use a certified NO2 calibration gas to perform a span calibration.
  • Follow the specific guidelines provided by the manufacturer for span calibration.

Adjustment Controls

  • If your device has adjustment controls for calibration, carefully follow the instructions to adjust as needed.

Verification

  • After calibration, verify the accuracy of the measurements by comparing them with known standard concentrations.

Record Calibration Details

  • Record details of the calibration, including the date, time, calibration gases used, and any adjustments made.
