Nitrogen Gas Analyzer Service Details:

Calibration: This is the core of the service. It involves adjusting the analyzer's sensor to a known standard. Nitrogen analyzers often measure the concentration of residual oxygen, as nitrogen purity is inversely proportional to oxygen content. The calibration process typically uses two-point calibration:

• Zero Calibration: The analyzer's reading is set to zero or a near-zero value using a gas that contains very little to no oxygen, such as high-purity nitrogen.
• Span Calibration: The analyzer's reading is adjusted to a known, higher concentration of oxygen, typically using a certified calibration gas or, in some cases, clean ambient air (which is approximately 20.9% oxygen).

Preventive Maintenance: This involves routine tasks to prevent future issues and extend the analyzer's lifespan. This includes:

• Cleaning or replacing filters (e.g., coalescing, carbon, and particulate filters).
• Inspecting and replacing worn parts like seals, o-rings, and valves.
• Checking for leaks in the sample gas lines and fittings using a leak detector.

Functional Checks: The service technician will verify that all components are working correctly, including the power supply, display, alarms, and data output systems.

Troubleshooting and Repair: If the analyzer is malfunctioning or fails to calibrate, the service includes diagnosing the problem and performing the necessary repairs, which may involve replacing the sensor, circuit boards, or other damaged components.
