Maintenance Tips for Gas-Leak Detection Equipment: Ensuring Safety and Reliability

by Jeet Sodagar on 26/09/25

Introduction

Gas-leak detection and flue gas monitoring equipment are essential for ensuring safety, compliance, and operational efficiency in industrial and commercial environments. Whether you are using portable gas detectors, fixed gas detectors, or Flue Emission Monitors (FEM) to measure boiler efficiency, proper maintenance is key to reliable performance. 

At ESPM Sense Pvt Ltd, we manufacture advanced gas detection solutions, including the FGD-X (Fixed Gas Detector), PGD-X (Portable Gas Detector), and FEM series for flue gas analysis, engineered for accuracy and durability in industrial conditions. In this blog, we share essential maintenance tips to keep your gas and flue emission monitoring equipment performing optimally. 

1. Understand Your Sensor Types

Different types of sensors are used depending on the target gas and application:

PID (Photoionization Detector): Detects volatile organic compounds (VOCs) and hazardous gases at low concentrations. Sensitive to contamination, requiring careful handling and maintenance. It can work accurately for prolong period without calibration. 

Catalytic Pellistor: Measures combustible gases such as methane, propane, and LPG. Requires regular calibration to maintain accuracy. 

Electrochemical Sensors: Ideal for toxic gases like CO, H2S, and NO2. Highly accurate for low-level detection but have limited lifespan and need periodic replacement. To maintain accuracy it requires regular calibration. 

It is preferred that sensor housing does not come to contact with any type of liquid or vapours directly.

2. Calibration 

Calibration ensures consistent performance across all devices:

Adjusts sensor output to match known gas concentrations. Recommended monthly or quarterly depending on application.

It is recommended to calibrate the equipment every 6 months regularly to ensure safe operation.

3. Battery and Power Maintenance

For portable detectors (PGD-X):

  • Charge batteries using approved chargers only.
  • Inspect and clean battery contacts to prevent corrosion. 

For fixed detectors like FGD-X or FEM units:

  • Ensure stable power supply, including UPS backup, to prevent downtime and sensor drift. 

5. Record-Keeping and Maintenance Logs

Maintain detailed logs to comply with safety regulations and track sensor performance:

  • Record calibration, bump tests, and sensor replacements.
  • Note unusual readings or environmental incidents.
  • Periodically review logs to identify trends and schedule preventative maintenance. 

Conclusion

Proper maintenance is critical for reliable gas detection and flue emission monitoring. By following these tips for PID, catalytic pellistor, and electrochemical sensors across FGD-X, PGD-X, and FEM units, you ensure safety, regulatory compliance, and operational efficiency.
