Operating a Nitric Oxide Gas Detector:

Power On/Off:

  • Ensure the gas detector is placed in the target area.
  • Follow the GAO Tek’s instructions to power on the device.
  • Allow the detector to go through its startup sequence.

Pre-operation Checks:

  • Inspect the device for any visible damage or loose connections.
  • Confirm that the sensors are clean and free from any obstructions.
  • Ensure the gas detector is appropriate for the specific NO concentration range you are monitoring.

Setting Alarms:

  • Set alarm thresholds based on the permissible exposure limits (PEL) or other relevant standards.
  • Verify that audible and visual alarms are functioning correctly.

Continuous Monitoring:

  • Allow the gas detector to operate continuously in the desired location.
  • Regularly check the display for real-time NO concentration readings.

 

Maintaining a Nitric Oxide Gas Detector:

Sensor Inspection:

  • Periodically inspect the sensor for any signs of physical damage or contamination.
  • Clean the sensor according to GAO Tek’s recommendations using appropriate cleaning solutions.

Battery Maintenance:

  • If the gas detector uses batteries, regularly check and replace them as needed.
  • Follow GAO Tek’s guidelines for battery replacement and disposal.

Calibration Checks:

  • Perform routine calibration checks to ensure the accuracy of the gas detector.
  • Inspect and replace calibration gas cylinders as necessary.

Bump Testing:

  • Conduct regular bump tests to verify that the gas detector responds to a known concentration of NO.
  • If the response is not within an acceptable range, perform a full calibration.

Record Keeping:

  • Maintain a record of maintenance activities, including sensor cleaning, calibrations, and any replacements.

 

Calibrating a Nitric Oxide Gas Detector:

Frequency:

  • Calibrate the gas detector according to GAO Tek’s recommendations.
  • Typically, calibrations are performed at regular intervals, such as monthly or quarterly.

Equipment Needed:

  • Calibrating gas cylinder with a known concentration of nitric oxide.
  • Calibration adapter or tubing if required.
  • Calibration kit provided by GAO Tek.

 

Calibration Procedure:

Zero Calibration:

  • In clean air or nitrogen environment, there are zero gas detectors. This establishes a baseline for accurate measurements.

Span Calibration:

  • Introduce the calibration gas with a known NO concentration.
  • Adjust the gas detector’s calibration span to match the concentration of the calibration gas.

Verification:

  • Check the gas detector readings against the expected values to ensure accurate calibration.

General Tips:

  • Always use the detector in accordance with GAO Tek’s guidelines.
  • Be aware of the lifespan of sensors, as they will need replacing after a certain period or number of exposures.
  • Ensure all personnel using the detector are adequately trained in its operation and interpretation of results.
