What is a significant drawback of telemetric gas monitoring systems?

Telemetric gas monitoring systems often require periodic calibration to ensure their accuracy and reliability. This calibration process can be manpower intensive, involving trained personnel to perform the adjustments and checks necessary to keep the system functioning correctly. Regular calibration is crucial because the sensors used in these systems can drift or become less accurate over time due to environmental factors and sensor wear. This reliance on manpower for calibration represents a significant drawback, as it means organizations must allocate resources and personnel to maintain the system effectively.

In contrast, cost-effective installation, low maintenance, and optimal performance in low-oxygen environments might reflect advantages of these systems or characteristics that do not directly relate to their drawbacks. Therefore, the focus on the manpower-intensive nature of the calibration process highlights a critical challenge faced by users of telemetric gas monitoring systems.
