Aquasol
POM-5B Oxygen Monitor
An ultra-high-purity Bluetooth oxygen monitor with an internal pump, 5 ppm resolution, and remote data logging.

The Aquasol POM-5B is designed for ultra-high-purity welding applications that require finer oxygen measurement than a 100 ppm monitor. Its rechargeable handheld unit uses an internal pump and measures oxygen concentration with 0.0005% (5 ppm) resolution.
Bluetooth connectivity supports compatible Android, iOS, and Windows devices, while real-time and offline data logging provides records for critical work. Operators can set alarm limits and use the colour-notification system for a quick reading status. Confirm the project oxygen limit, logging and inspection requirements, sampling location, calibration procedure, accessories, and site environment before selection.
