The OMD-21 Portable Handheld Oxygen Analyser provides accurate, convenient oxygen measurement in a compact, easy-to-use design. Ideal for scuba diving, technical diving, welding and industrial applications, this portable oxygen analyser allows users to quickly check oxygen concentrations in gas cylinders and other compatible gas supplies. With a 0–100% oxygen measurement range, it is particularly useful for verifying oxygen content in enriched air nitrox and other diving gas mixtures.
Featuring advanced galvanic electrochemical sensor technology, the OMD-21 delivers stable, reliable oxygen measurements with minimal maintenance. Its self-contained sensor eliminates the need for electrode cleaning or electrolyte replacement, making it a practical choice for regular gas analysis. The large backlit display and user-friendly menu provide clear readings and straightforward operation, even in low-light environments.
For added safety and convenience, the OMD-21 features configurable high and low audible oxygen alarms, allowing users to set their preferred alarm limits or silence the alarms when required. The flexible coiled sensor cable extends up to 12 feet (approximately 3.66 metres), providing additional reach when analysing cylinders or gas supplies.
Designed for portability, the analyser operates on three AAA batteries, included with the unit, making it convenient for use in dive shops, filling stations, workshops and field environments. A flow-through diverter and blue tee adaptor are also included for compatible gas sampling applications.
Whether checking nitrox mixtures before a dive or monitoring oxygen concentrations in industrial applications, the OMD-21 Handheld Oxygen Analyser combines accurate measurement, convenient operation and low-maintenance performance in one portable instrument.
