Background and Identification

The Greisinger GOX 100 Oxygen Analyzer (Item Part Number: ‎600222 and ASIN: B004JIWOUS) gauges oxygen potencies in air and gas mixtures. This device is multipurpose but is primarily used by medical professionals to measure these levels without opening a patient's pneumatic anesthesia system.

Greisinger, a member of the GHM group (a collection of German technology companies), has been dedicated to producing high-quality electronic measuring devices for over 35 years. This device can be found at multiple locations online and typically costs between two to three hundred U.S. dollars. This product provides an Auto-Power off mode when not in use to limit unnecessary battery life consumption.

The GOX 100 is a small (106 x 67 x 30 mm) black hand-held box with blue buttons and a 13 x 40 mm display screen. This device has %O2 above the display, the model number (GOX100) is located just below the display screen, and the manufacturer's name (Greisinger) is at the bottom of the screen below the three user-interface keys (buttons).
