Common failures & inspection points

Sensor poisoning, ageing, contamination, or end-of-life degradation causes slow response, failed calibration, or readings that drift from known test gas
Blocked sample line, filter, pump, or diffusion path prevents representative gas reaching the sensor and causes low or delayed readings
Battery, supply, charger, or internal power faults cause shutdown, short operating time, or power alarms
Water ingress, condensation, corrosion, or damaged connectors produces intermittent channels, false alarms, or failed communication
Calibration, configuration, relay, or control faults can cause nuisance alarms, missing alarms, or incorrect display of the monitored point

Service & Maintenance

Inspect sensor condition, sampling paths and filters, pump operation where fitted, battery or power supply, alarms, relays, display, identification of sampling points, and calibration records. Perform bump tests and calibration only with approved gas and according to the manufacturer and vessel safety procedure.
