Calibration and alarm verification of an OVMS-50 oxygen monitoring system to ensure safe inert gas operations onboard tankers.

Reliable oxygen monitoring is a critical safety requirement on tanker vessels, especially during inert gas operations where incorrect readings can lead to serious risks. Oxygen monitoring systems must not only display accurate values but also trigger alarms correctly when conditions change.

This image shows an OVMS-50 Oxygen Monitoring & Alarm Unit from Hanla IMS during a calibration and full function health check onboard. The process includes verification of oxygen concentration readings, flow detection, alarm activation, and overall system status to ensure the unit performs exactly as intended.
