Why Replace Your Catalytic LEL Sensor?

Catalytic bead sensors gradually lose sensitivity due to prolonged exposure to combustible gases, environmental conditions, and normal aging. Routine replacement helps maintain accurate gas detection and reduces the risk of undetected combustible gas hazards.

Common signs that replacement may be necessary include:

• Calibration failures

• Slow sensor response

• Inaccurate or unstable readings

• Sensor fault or diagnostic alarms

• Scheduled preventive maintenance intervals

• Reduced sensitivity caused by catalyst poisoning or aging

Replacing the sensor is a cost-effective way to extend the life of your gas detection system while maintaining reliable combustible gas monitoring.
