Orbitalum ORBmax Digital Oxygen Analyzer Designed for use with orbital welding power supplies, the ORBmax oxygen analyzer measures and monitors oxygen particle count with great accuracy. The ORBmax eliminates uncontrolled, unmonitored purging and presumption of acceptable oxygen levels required for exacting weld standards. With its maintenance free optical sensor, the ORBmax measures oxygen PPM with high precision to ensure highly repeatable, oxidation free welds. Requiring no warm up time, the ORBmax displays a large numerical oxygen particle count in PPM on a user friendly touch screen. The display doubles as an input device, and changes color from red to green to indicate when the preset oxygen value has been reached. The unit also features an alarm mode with an audible warning should the oxygen content rise above the preset PPM level. These measured values can be digitally logged and saved via a user selectable save interval to an SD card for purge documentation. The ORBmax features a compact, rugged water and dust resistant enclosure with a built in air pump allowing for active and passive oxygen content measurement. The unit comes with a protective cover that doubles as a solid table stand for easier viewing of the display. The ORBmax is a “must have” for the highly controlled, high purity welding requirements commonly found in the semiconductor, pharmaceutical and aerospace industries, or any application where oxygen levels need monitoring. The ORBmax interfaces with Orbitalum‘s OM series of orbital welding power supplies to prevent the start of a welding program until the user defined oxygen value has been reached. These measured values can be digitally logged and saved via a user selectable save interval to an SD card for purge documentation.
