• Impact: False negatives, undetected leaks, safety risks, system inefficiency.
• Mitigation:
• Specify detectors with <5 ppm sensitivity.
• Require third-party calibration certificates (e.g., NIST-traceable).
• Prefer electrochemical or catalytic bead sensors with drift compensation.

b. Lack of Selectivity (Cross-Sensitivity)

• Pitfall: Some sensors react to non-target gases (e.g., CO, methane, alcohol vapors), causing false positives.
• Impact: Wasted time troubleshooting non-existent leaks; reduced operator trust.
• Mitigation:
• Choose detectors with high H₂ selectivity (e.g., membrane-filtered sensors).
• Test in environments with common interferents before deployment.

c. Inadequate Build Quality & Durability

• Pitfall: Units from unknown manufacturers may use substandard materials (e.g., brittle probes, weak housings), failing in field conditions.
• Impact: Short device lifespan, frequent repairs, downtime.
• Mitigation:
• Look for IP65 or higher ingress protection.
• Require compliance with IEC 61010 (safety) and ISO 9001 (quality management).

d. Poor Calibration & Maintenance Support

• Pitfall: Vendors may not offer accessible calibration services or spare parts, especially outside their home region.
• Impact: Detector drifts out of spec; becomes unreliable over time.
• Mitigation:
• Confirm local service centers or in-house calibration capability.
• Choose brands with long-term support history.

e. Inaccurate Leak Quantification

• Pitfall: Some devices only give qualitative “beep” feedback, not quantitative leak rate (e.g., cc/min or g/year).
• Impact: Cannot prioritize repairs or meet regulatory reporting.
• Mitigation:
• Require digital readout with leak rate estimation.
• Ensure device supports H₂/N₂ mix (typically 5% H₂ / 95% N₂) traceability.
